Batteries are arguably the most vital component of an electric bike. As a new or versatile e-bike user, we believe you are aware of the importance of an e-bike battery. However, there is a popular question that most e-bike users ask. How do you choose the right battery for your electric bike? How do you know which one is the best of all the varieties of available battery types? What type of cell do I purchase for my electric bike? Basic e-bike battery terminologies Before choosing the best battery for your e-bike, you have to be able to understand the terminology used to describe e-bike batteries. We will define a few terminologies. This will help you understand more about your batteries. Here is a list of the most common terms used when discussing e-bikes: Amperes (Amps) Ampere per hour (Ah) Voltage (V) Watts (W) Watt per hour (Wh) Amperes (Amps) This is the unit of electrical current. It is an international standard unit. You can compare amperes to the size or diameter of a pipe with water passing through it. This would mean more amperes means a bigger pipe with more water inflow per second. Ampere per hour (Ah)  This is a unit of electrical charge, with dimensions of electric current against time. It is an indicator of the battery capacity. A battery of about 15Ah can discharge 1.5A for ten (10) hours continuously or discharge 15A for an hour continuously. Voltage (V) This is commonly known as volts. It is the electrostatic potential difference between two (2) conductors (Live and Neutral conductors). The best electric bike battery voltage reading is 400 volts. Watts (W) This is a standard unit of power. The higher the number of watts, the higher the power output from your electric bike. Also, one (1) watt ...

The batteries are one of the important components of an electric bike (e-bike). The batteries will influence the speed and duration of the e-bike. Many people will choose to refit or DIY an e-bike of their own to provide more horsepower or tailor a unique style. So what battery should we choose for an e-bike? Lead-acid Electric Bike Batteries (SLA) Lead-acid batteries are relatively cheap and easy to recycle. Lead is one of the most effectively recycled materials in the world and today more lead is produced by recycling than is mined. However, they need to maintain usually, and they don’t last very long. It is not a good choice if you’re serious about actually using your bike to commute. Lead-acid batteries are cheap for several reasons: Cheap of raw materials; They weigh twice as much as NiMh batteries, and three times as much as lithium batteries. They have much less usable capacity than NiMh batteries or lithium batteries. Only last for half as long as nickel or lithium batteries. However, lead-acid batteries have been gradually replaced by lithium iron phosphate (LiFePO4) batteries. At the same time, that battery costs have fallen, the lifespan and average cost of lithium iron phosphate batteries have been falling. Nickel-cadmium (NiCd) Electric Bike Batteries Weight for weight, nickel-cadmium (NiCd) batteries have more capacity than a lead-acid battery, and capacity is an important consideration on an electric bike. However, nickel-cadmium is expensive and cadmium is a nasty pollutant and hard to recycle. On the other hand, NiCd batteries will last longer than lead-acid batteries. But the reality is that because they are so hard to recycle or get rid of safely, NiCd batteries are rapidly becoming a thing of the past. These are also not a good choice of battery type, regardless of price. Lithium-ion (Li-ion) Electric Bike Batteries This is a new one and ...

Solar energy is a fantastic way to get power anywhere the sun shines. It works great but only when the sun is out, so it’s critical to have the best battery possible for storing solar energy. LiFePO4 battery chemistry is one of the best options for solar storage for a number of reasons. Join us as we take a closer look at the best option for storing the sun’s energy. What Is Solar Battery Storage? First, let’s simply define solar battery storage. Solar panels convert sunlight into energy, but you can’t always count on having enough sunlight to provide consistent power on demand. If it’s overcast or nighttime, you’d be out of luck without a good battery. When the solar panels absorb the power, it is transferred to the battery until it reaches capacity. You can use the power stored within when it’s overcast or night and rely on fresh solar power when it’s sunny. The battery can also provide a larger amount of energy for a short period of time. It is possible to run a 1200 watt microwave on a 300-watt solar panel, but only if you have a batter to store and provide the larger amount of energy for a shorter period. The battery is the heart of the solar system because none of the other components are much help without it. Solar Battery Storage Options As you might have gathered from the title, LiFePO4 is our top choice and what we specialize in at dragonfly energy. It stands head and shoulders above traditional lead-acid batteries of all types, and we consider it the best lithium battery option for solar. Here are a few of the most common types of solar battery storage options Lead-Acid Batteries Lead-acid batteries are likely the most familiar type that can be ...

When it comes to LiFePO4 vs lithium ion, LiFePO4 is the clear winner. But how do LiFePO4 batteries compare to other rechargeable batteries on the market today? Lead Acid Batteries Lead acid batteries may be a bargain at first, but they’ll end up costing you more in the long run. That’s because they need constant maintenance, and you must replace them more often. A LiFePO4 battery will last 2-4x longer, with zero upkeep needed. Gel Batteries Like LiFePO4 batteries, gel batteries don’t need frequent recharging. They also won’t lose charge while stored. Where do gel and LiFePO4 differ? A big factor is the charging process. Gel batteries charge at a snail’s pace. Also, you must disconnect them when 100% charged to avoid ruining them. AGM Batteries AGM batteries will do plenty of damage to your wallet, and are at high risk for becoming damaged themselves if you drain them past 50% battery capacity. Maintaining them can be difficult as well. LiFePO4 Ionic lithium batteries can be discharged completely with no risk of damage. A LiFePO4 Battery for Every Application LiFePO4 technology has proven beneficial for a wide variety of applications. Here’s a few of them: Fishing boats and kayaks:Less charging time and longer runtime means more time out on the water. Less weight allows for easy maneuvering and a speed boost during that high-stakes fishing competition. Mopeds and mobility scooters:No dead weight to slow you down. Charge to less than full capacity for impromptu trips without damaging your battery. Solar setups:Haul lightweight LiFePO4 batteries wherever life takes you (even if it’s up a mountain and far from the grid) and harness the power of the sun. Commercial use:These batteries are the safest, toughest lithium batteries out there. So they’re great for industrial applications like floor machines, liftgates, and more. Much ...

Why is LiFePO4 battery so popular? The LiFePO4 battery is a type of Lithium-ion battery. It is one of the safest and most eco-friendly battery because of its non-toxicity, high energy density, low self-discharge, fast charging and long life span. Because of these characteristics, it has now become the most mainstream battery, widely used in light electric vehicles, energy storage equipment for solar and wind power generation, UPS and emergency lights, warning lights and mining lights, power tools, toys such as remote control cars/boats/airplanes, small medical instruments and equipment and portable instruments, etc . Let’s have an insight into this revolutionary technology below. Amazing Light Weight and High energy density A lithium iron phosphate battery of the same capacity is 2/3 the volume and 1/3 the weight of a lead-acid battery. Less weight means more maneuverability and speed. The small size and lightweight are well suited for applications like solar energy systems, RVs, golf carts, bass boats, electric vehicles, and similar ones. Meanwhile, LiFePO4 batteries have a high storage energy density, having reached 209-273Wh/pounds, about 6-7 times that of lead-acid batteries. For example, 12V 100Ah AGM battery weighs 66pounds, while an Ampere 12V 100Ah LiFePO4 battery of the same capacity weighs only 24.25pounds. Highest Efficiency with Full Capacity As most LiFePo4 batteries are used for deep cycle applications, their 100% Depth of Discharge (DOD) plays a vital role in providing great efficiency. Lead-acid batteries can only be discharged to 50% at 1C discharge rate, unlike lithium batteries. So, right here, you already need two lead-acid batteries to make up for one lithium battery, which means space and weight savings. Finally, people are sometimes turned off by the upfront cost of lithium batteries, but you don't have to replace them every three to five years like you do with lead-acid batteries. 10X Cycle life than Lead Acid Batteries LiFePo4 ...

LiFePO4 batteries are taking “charge” of the battery world. But what exactly does “LiFePO4” mean? What makes these batteries better than other types? Read on for the answer to these questions and more. What are LiFePO4 Batteries? LiFePO4 batteries are a type of lithium battery built from lithium iron phosphate. Other batteries in the lithium category include: Lithium Cobalt Oxide (LiCoO22) Lithium Nickel Manganese Cobalt Oxide (LiNiMnCoO2) Lithium Titanate (LTO) Lithium Manganese Oxide (LiMn2O4) Lithium Nickel Cobalt Aluminum Oxide (LiNiCoAlO2) You might remember some of these elements from chemistry class. That’s where you spent hours memorizing the periodic table (or, staring at it on the teacher’s wall). That’s where you performed experiments (or, stared at your crush while pretending to pay attention to the experiments). Of course, every now and then a student adores experiments and ends up becoming a chemist. And it was chemists who discovered the best lithium combinations for batteries. Long story short, that’s how the LiFePO4 battery was born. (In 1996, by the University of Texas, to be exact). LiFePO4 is now known as the safest, most stable and most reliable lithium battery. LiFePO4 vs. Lithium Ion Batteries Now that we know what LiFePO4 batteries are, let’s discuss what makes LiFePO4 better than lithium ion and other lithium batteries. The LiFePO4 battery isn’t great for wearable devices like watches. Because they have a lower energy density compared to other lithium-ion batteries. That said, for things like solar energy systems, RVs, golf carts, bass boats, and electric motorcycles, it’s the best by far. Why? Well, for one, the cycle life of a LiFePO4 battery is over 4x that of other lithium ion batteries. It’s also the safest lithium battery type on the market, safer than lithiom ion and other battery types. And last but not least, LiFePO4 batteries can ...

This year, renewable power is growing robustly around the world, contrasting with the sharp declines triggered by the COVID-19 crisis in many other parts of the energy sector, such as oil, gas and coal, according to a recently released report from the International Energy Agency (IEA). Driven by China and the U.S., new additions of renewable power capacity worldwide will increase to a record level of almost 200 GW this year, the IEA’s Renewables 2020 report forecasts. This rise – representing almost 90% of the total expansion in overall power capacity globally – is led by wind, hydropower and solar PV. Wind and solar additions are set to jump by 30% in both the U.S. and China as developers rush to take advantage of expiring incentives. Even stronger growth is to come. India and the EU will be the driving forces behind a record expansion of global renewable capacity additions of nearly 10% next year – the fastest growth since 2015 – according to the report. This is the result of the commissioning of delayed projects where construction and supply chains were disrupted by the pandemic, and growth in markets where the pre-COVID project pipeline was robust. India is expected to be the largest contributor to the renewables upswing in 2021, with the country’s annual additions doubling from this year. “Renewable power is defying the difficulties caused by the pandemic, showing robust growth while other fuels struggle,” says Dr. Fatih Birol, executive director of the IEA. “The resilience and positive prospects of the sector are clearly reflected by continued strong appetite from investors – and the future looks even brighter with new capacity additions on course to set fresh records this year and next.” Policy makers still need to take steps to support the strong momentum behind renewables. In the IEA report’s main forecast, the ...

Different Lithium Technologies Firstly, it is important to note that there are many types of “Lithium Ion” batteries. The point to note in this definition refers to a “family of batteries”. There are several different “Lithium Ion” batteries within this family which utilize different materials for their cathode and anode. As a result, they exhibit very different characteristics and therefore are suitable for different applications. Lithium Iron Phosphate (LiFePO4) Lithium Iron Phosphate (LiFePO4) is a well-known lithium technology in Australia due to its wide use and suitability to a wide range of applications. Characteristics of low price, high safety and good specific energy, make this a strong option for many applications. LiFePO4 cell voltage of 3.2V/cell also makes it the lithium technology of choice for sealed lead acid replacement in a number of key applications. Why LiFePO4? Of all the lithium options available, there are several reasons why LiFePO4 has been selected as the ideal lithium technology for replacement of SLA. The main reasons come down to its favourable characteristics when looking at the main applications where SLA currently exist. These include: Similar voltage to SLA (3.2V per cell x 4 = 12.8V) making them ideal for SLA replacement. Safest form of the lithium technologies. Environmentally friendly –phosphate is not hazardous and so is friendly both to the environment and not a health risk. Wide temperature range. Features and benefits of LiFePO4 when compared to SLA Below are some key features LiFePO4 batteries which give some significant advantages of SLA in a range of applications. This is not a complete list by all means, however it does cover the key items. A 100AH AGM battery has been selected as the SLA, as this is one of the most commonly used sizes in deep cycle applications. This 100AH AGM has been ...

Lithium-ion battery is widely used in the energy storage system. When purchasing lithium battery,we need to know the main parameters of lithium-ion battery. 1.Battery Capacity Battery capacity is one of the important performance indicators to measure the performance of the battery. It represents the amount of Electricity discharged by the battery under certain conditions (discharge rate, temperature, termination voltage, etc.) Nominal voltage and nominal ampere hours are the most basic and core concepts of batteries. Electricity (Wh)=Power (W)*Hour(h)=Voltage (V)*Amp-hour(Ah) 2.Battery discharge rate Reflects the battery charge-discharge capacity rate; charge-discharge rate=charge-discharge current/rated capacity. It represents speed of discharge. Generally, the capacity of the battery can be detected by different discharge currents. For example, when a battery with a battery capacity of 200Ah is discharged at 100A, its discharge rate is 0.5C. 3.DOD (Depth of Discharge) It refers to the percentage of the battery's discharged capacity to the battery's rated capacity during battery use 4.SOC (State of charge) It represents the percentage of the battery's remaining power to the battery's rated capacity. 5.SOH (State of Health) It refers to the battery health status (including capacity, power, internal resistance, etc.) 6.Internal resistance of battery It is an important parameter to measure the performance of the battery. The large internal resistance of the battery will reduce the working voltage of the battery when discharging, increase the internal energy loss of the battery, and aggravate the heating of the battery. The internal resistance of battery is mainly affected by many factors, such as battery material, manufacturing process, battery structure and so on. 7.Cycle life It refers to the number of charging and discharging cycles that the battery can withstand before its capacity decays to a specified value under certain charging and discharging conditions. One cycle refers to one full charge and one full discharge. The ...

Electric Bike Batteries: Size Matters One of the most important components of any electric bike is the BATTERY, but it’s surprisingly overlooked by many riders when they make their first e-bike purchase.  And it’s universally cited as one of the biggest complaints among new riders after they buy their first e-bike: ‘I wish I would have bought an e-bike with a bigger battery’ Ultimately, the size of the battery determines how much power, speed and range you can expect from your new e-bike. If you’re interested in power, speed or range, then pay close attention to battery size. The majority of e-bikes currently available today are based around a  36 or 48-Volt battery; typically providing very modest power, speed and hill climbing performance. The higher voltage packs fuels considerably more power, more speed and higher efficiency for a more enjoyable ride. The 52V battery system has been used by “hot-rodders” to achieve a higher level of e-bike performance compared to the standard  48V systems. Over the last decade,  Bikes has engineered and built the necessary infrastructure to make a turn-key 52V battery available on every  electric bike. Key Advantages of the 52-Volt Platform More Power: Power is essentially amps multiplied by voltage: higher voltage = more power. All Juiced Bikes batteries use High Rate Cells and up to 45Amps Max current (nearly double the industry standard). More speed: Electric motors naturally spin faster with high voltage. Our higher voltage systems allow all of our e-bikes to reach Class 3 (28MPH) performance, with some models exceeding 30MPH throttle-only speeds, while still providing great hill climbing torque desired by e-bike enthusiasts. More Range: Powering a riding range of up to 100 miles per charge, our massive 52V batteries offer an unparalleled value in the e-bike market and possibly one of the most important differences ...

With lithium batteries becoming a more common option in our daily life, and Lithium battery come to use in our a lot of areas. Do you go with the traditional AGM or move to lithium? Here are a few tips to weigh the benefits of each battery type for our customer and help you make a more informed decision. Lifespan and Costs Budgets play a huge role in deciding which battery to get. With Lithium batteries being more expensive to begin with, it can seem like a no-brainer to go with an AGM. But what causes this difference? AGM batteries remain less expensive because the materials used to make them are inexpensive and widely available. Lithium batteries, on the other hand, use more expensive materials with some being harder to come by (i.e. lithium). Another part of the decision-making process to consider is the lifespan of these batteries. This is where the initial cost of the Lithium could be offset. The following points highlight the differences between lithium and AGM: AGM batteries are sensitive to depth of discharge. This means the deeper the battery is discharged, the fewer cycles it has. AGM batteries are generally recommended to only be discharged to 50% of their capacity to maximize their cycle life. This limited depth of discharge (DOD) of 50% means that more batteries are required to achieve the desired capacity. This means more upfront costs, and more space needed to store them. A lithium (LiFePO4) battery, on the other hand, is not affected much by depth of discharge so it boasts a much longer cycle life. Its DOD of 80-90% means fewer batteries are required to achieve the desired capacity. Fewer batteries mean less space needed to store them. More on discharge depths later. Initial Cost Per Capacity ($/kWh): AGM – 221; Lithium – 530 Initial ...

When it comes to the words’ lithium battery’ it’s safe to say that lately, these two words have generated a lot of confusion, fear, and speculation. So, it’s no wonder you might ask yourself, “why on Earth would anyone use Lithium batteries?” But rest assured, we’ve done our homework. At ALL IN ONE, we’ve dedicated over a decade of our time on, research & development, learning, design, and the optimization of our products, to ensure that we always provide customers with safe technology and innovative solutions. Before we can get into what makes our Lithium batteries safe, let’s cover the basics.Lithium 101 Lithium was discovered in 1817 by Swedish Chemist, Johan August Arfwedson. You might remember seeing “Li,” on the periodic table on your school teacher’s wall, but Arfwedson first called it ‘lithos’, which means stone in Greek. Li is a soft, silvery-white alkali metal and its high-energy density makes it a great choice to give batteries an extra boost. The “Lit” in Lithium batteries According to Power Electronics, there are 6 different types of Lithium-ion batteries, ranging from Lithium Cobalt Oxide (LiCoO22) batteries to Lithium Nickel Manganese Cobalt Oxide (LiNiMnCoO2) batteries and Lithium Titanate (LTO) batteries. Historically, Lithium batteries like Lithium-ion or Lithium Polymer offered distinct advantages over their other Lithium battery counterparts because of their longevity, reliability, and capacity. However, Lithium-ion/polymer batteries proved problematic and needed to be handled with care, precisely because of their “thermal runaway” and proneness to exploding or catching on fire. But, thanks to the progress made in the Lithium battery and technology industries, more stable and safer batteries were developed, like our Lithium Iron Phosphate (LiFePO4) battery. Now that you are up-to-speed with all-things Lithium, here are our 5 reasons why we opt to use Lithium Iron Phosphate (LiFePO4) technology. 1. Safety: LiFePO4 is ...

A battery management system is essentially the “brain” of a battery pack; it measures and reports crucial information for the operation of the battery and also also protects the battery from damage in a wide range of operating conditions. The single most important function that a battery management system performs is cell protection. Lithium ion battery cells have two critical design issues; if you overcharge them you can damage them and cause overheating and even explosion or flame so it's important to have a battery management system to provide overvoltage protection . Lithium ion cells can also be damaged if they're discharged below a certain threshold, approximately 5 percent of total capacity. If the cells are discharged below this threshold their capacity can become permanently reduced. To ensure a battery's charge doesn't go above or below its limits, a battery management system has a safeguard device called a dedicated Lithium-ion protector Every battery protection circuit has two electronic switches called "MOSFETs." MOSFETs are semiconductors used to switch electronic signals on or off in a circuit. A battery management system typically has a Discharge MOSFET and a Charge MOSFET. If the protector detects that the voltage across the cells exceeds a certain limit, it will discontinue the charge by opening the Charge MOSFET chip. Once the charge has gone back down to a safe level then the switch will close again. Similarly, when a cell drains to a certain voltage, the protector will cut off the discharge by opening the Discharge MOSFET. The second most important function performed by a battery management system is energy management. A good example of energy management is your laptop battery's power meter. Most laptops today are not only able to tell you how much charge is left in the battery but also what your rate ...
