AGM battery has the advantages of low cost and large discharge current, but it has the defects of narrow working temperature range, easy loss of water and thermal runaway; GEL battery has high cost, but it has the advantages of stable performance, wide operating temperature range, over charging and over discharging resistance, long life, etc.
As the electric bicycle battery is subject to high current and deep cycle discharge in most cases, the electric bicycle battery is more suitable for colloid battery. Colloid battery has strong over discharge resistance and strong electrohydraulic storage capacity, which avoids the impact of over discharge on the battery and thermal runaway caused by battery water loss.
The charging characteristics of various brands of lead-acid batteries are basically the same. However, due to the different battery material formulations, electrolyte concentrations and contents of different manufacturers, their charging voltages are also different. Therefore, strictly speaking, the charging voltage scheme of the battery should be determined according to the specific requirements given by the battery manufacturers, otherwise it is easy to cause improper use of the battery.
The output power of the electric bicycle motor should match the rated power of the battery. Therefore, in order to prolong the service life of the battery, the motor power of the electric bicycle should be less than the rated power of the battery as much as possible to avoid the battery working under full load or overload conditions for a long time.
