The key points of battery purchase

Because electric bicycle batteries are high-current, deep-cycle discharge in most cases, gel batteries are more suitable for electric bicycle batteries. Gel batteries have strong over-discharge resistance and strong electro-hydraulic storage capacity. This avoids the impact of over-discharge on the battery and the occurrence of thermal runaway due to battery loss.

The charging characteristics of various brands of lead-acid batteries are basically the same. However, due to the different battery material formulations, electrolyte concentration and content of various manufacturers, their charging voltages also have certain differences. Therefore, the charging voltage scheme of the battery should be determined according to the specific requirements given by each battery manufacturer. Otherwise, it is easy to cause improper use of the battery.

The output power of the electric bicycle motor must match the rated power of the battery. Therefore, in order to extend the service life of the battery, the motor power of the electric bicycle should be as small as possible than the rated power of the battery. It is necessary to avoid long-term operation of the battery under full load or overload conditions.
