AGM battery has the advantages of low cost, high discharge current, but there is a working temperature range, battery water and thermal runaway of the defect and GEL batteries are expensive, but with stable performance, wide temperature range, charging after discharging resistance, long life and other advantages.
Due to electric bike batteries in most cases belong to large currents, deep cycle discharge, so the electric bicycle battery selection more suitable for gel batteries. Gel battery with strong resistance to discharge capacity and strong electro-hydraulic storage to avoid over discharge of the battery effect, as well as the battery thermal runaway phenomena caused by water loss.
Brand charging characteristic of the lead-acid battery is basically the same, but because the manufacturers of battery materials, electrolyte concentrations and contents are different, the charging voltage has some differences, therefore, strictly speaking, should be according to the battery manufacturer's specifications to determine if the battery charging voltage scheme, otherwise easily lead to improper use of the battery.
Electric Bicycle motor power output to match the battery's rated power, so if you want to extend the life of batteries, electric bicycle motor power to be less than the rated power battery as far as possible, avoid battery at full capacity for a long time or overload conditions.
