    Types of electric motorcycle batteries

    The main power batteries that can be used by electric motorcycle on the market are the following: valve-regulated lead-acid maintenance-free batteries, colloidal lead-acid batteries and lithium-ion batteries.

    Lead-acid batteries are mature and cheap and are used in most electric vehicles. Lithium batteries have the advantages of being light in size, having a longer life, and having a long range. They are generally used in electric bicycles or high-end electric motorcycles.

    The main parameters of the electric motorcycle battery

    Electric motorcycle battery is generally divided into 10AH, 12AH, 16AH, 20AH, 32AH, 40AH, etc., and there is a parameter of 36V, 48V, 60V, 64V, 72V, and the corresponding power is generally 120W, 180W, 360W, 400W, 500W and so on.

    The main parameters of the electric motorcycle battery

    What exactly do these parameters mean

    V represents the voltage of the battery, and the higher the value, the faster the speed. AH represents capacity of the battery, and the higher the value, the stronger the endurance. W represents the battery power, the higher the number, the more power is consumed.

    Electric motorcycle battery range

    The endurance of electric motorcycle battery is usually related to batteries, motors, controllers, tires, on-board electrical appliances, load and so on. But the most important thing is the motor and battery, and the common electric motorcycle battery configuration is as follows:

    Three batteries (36V12A), four small batteries (48V12A), four large batteries (48V20A), five large batteries (60V20A), and six large batteries (72V20A).

    Usually speed and endurance are inversely proportional, the faster the car drives, the shorter the endurance, and the longer the endurance at a constant speed.

    • Brief summary

    How far can a 48-volt electric car go? The range of the 48-volt 12AH will not exceed 36 km, while the range of the 48-volt 20AH will not exceed 60 km.

    How far can a 60-volt electric vehicle go: The theoretical range of a 60-volt 20AH electric vehicle will not exceed 70 kilometers, and the theoretical range of a 72-volt 32AH electric vehicle will not exceed 90 kilometers.

    How far can a 72-volt electric car go: The theoretical range of a 72-volt 32AH can reach 100 kilometers, while the theoretical range of a 72-volt 45AH electric vehicle can reach 130 kilometers.

    Of course, the above is only the result of theoretical calculations, and the actual battery life depends on the quality, life and driving habits of the battery.

    Choose a lithium battery or a lead-acid battery

    The battery models for electric motorcycles are 60V, 72V, as well as lead-acid batteries and lithium batteries. How to buy them? In this regard, we can analyze it from three perspectives, namely price, battery life and safety.

    • Price

    Due to the high price of lithium batteries, lead-acid batteries are still the mainstream choice in the electric vehicle market. But lithium batteries are safer and more environmentally friendly. In the long run, lithium batteries have higher returns because they do not require maintenance.

    • Battery life

    According to the general formula for endurance calculation, the mileage of a 72V, 20Ah lead-acid battery is generally 60–70 km. If you are riding at medium or slow speed, the cruising range can reach about 80 km.

    The range of the 72V, 20Ah lithium battery is similar to that of lead-acid batteries, but the battery volume is at least three times smaller than that of lead-acid batteries.

    At the same time, the standard capacity of lead-acid batteries is only 12 Ah, 20Ah, and 32 Ah. Three gears are optional, while the lithium battery capacity is very high.

    • Safe

    Due to the current chaotic electric motorcycle battery market, lithium battery technology is becoming more and more mature. Lead-acid batteries are at risk of acid corrosion when replaced, and vehicle exhaust has an impact on the environment. Lithium batteries are now commonly used as electric motorcycle batteries.

    3 Ways to increase the range of electric motorcycle batteries

    The biggest impact of an electric vehicle’s power loss is the motor, and the choice of motor is the key. Usually, it is enough to pay attention to the configuration of the electric motorcycle battery and motor, and there are some tips for the selection of the motor.

    • Motor selection

    When the manufacturer is mainly equipped with an electric vehicle, the manufacturer starts selecting the factory-equipped motor according to the price of the electric vehicle. Like top 10 electric motorcycle manufacturers.

    Big brand high-end models generally choose motors with long life, durability, reliable performance and power savings. Motors of average quality will appear, resulting in large power consumption, loud noise, and a slow starting speed.

    The most serious point is that demagnetization is relatively fast in several years, power consumption will increase, and bearings will be damaged quickly.

    The good reason for the quality of the motor is that the motor manufacturing process is fine, there are many materials inside, the structure application is very reasonable, the running performance is stable, and the loss of time is relatively long.

    Benlg has successively developed high-performance motors equipped on high-end electric vehicles, and cooperates with energy recovery systems to reduce power loss, power utilization, and increase cruising range anxiety.

    3 ways to increase the range of electric motorcycle batteries

    Electric motorcycle battery and motor are reasonably configured.

    • Specifications are equipped

    Electric motorcycles have a fixed voltage and power, generally 48V350 ~ 400W. Such as 60V20Ah battery, with 600~800W motor is reasonable. 72V20Ah battery, with reasonable 800~1000W motor.

    • The weight of the entire vehicle

    The heavier the load weight of an electric vehicle, the higher the power consumption. Including the weight of the vehicle body and the personnel carrying it, as well as the cargo, have an impact.

    When buying a car to see the quality, you need the weight of the car. More endurance is slightly lighter, wanting to run farther, fewer people, less cargo.

    • Price point selection

    High-end and high-quality cars usually sell at a relatively high price. Choosing a low-priced battery configuration is small, and the quality of various spare parts is poor, and the high price will be better.

    Therefore, mastering these three points, we must pay attention to the purchase choice of electric vehicles, choose good quality, large battery configuration, and want to have a long battery life.

    You need to configure the motor with a small one. If you want to be fast and powerful, the motor choice will be better and the battery life will be reduced. Also check electric tricycle.

    It has been suggested that the larger the electric motorcycle battery capacity, the longer the endurance, which depends on the configuration of the motor power. If the motor power is properly matched, your car will have a long battery life, and if the power is large, the battery life will be less.

    Conclusion

    Under the premise that safety can be guaranteed, if you want to pursue high battery life, then large-capacity lithium batteries are your only choice. The range of electric vehicles is also affected by a number of factors, including brake tightness, high-speed speed, tire pressure, and loss due to aging motors.
