What are the key points for purchasing electric bicycle batteries?

AGM battery has the advantages of low cost and large discharge current, but it has the defects of narrow operating temperature range, battery loss of water and thermal runaway; while GEL battery has high cost, but it has stable performance, wide operating temperature range and over-endurance. Advantages of over-discharge and long life.
Since electric bicycle batteries are high-current, deep-cycle discharge in most cases, gel batteries are more suitable for electric bicycle batteries. Gel batteries have extremely strong over-discharge resistance and extremely strong electro-hydraulic storage capacity, which 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 formulas, electrolyte concentration and content of various manufacturers, their charging voltages also have certain differences. Therefore, strictly speaking, it should be based on each battery manufacturer. The specific requirements are given to determine the charging voltage scheme of the battery, otherwise it is easy to cause improper use of the battery.
The output power of the electric bicycle motor must match the battery's rated power. Therefore, in order to prolong the service life of the battery, the electric bicycle's motor power should be less than the battery's rated power as much as possible to prevent the battery from working under full or overload conditions for a long time.
