Battery purchase points

AGM batteries have a low cost, the advantages of a large discharge current, but there is a narrow temperature range, the battery is easy to dehydration and thermal runaway defects; and GEL batteries are costly, but with stable performance, wide operating temperature range, resistance to over charging over-discharge, long life and other advantages.
As the Electric Tricycles batteries in most cases is a large current, deep discharge cycles, therefore, the electric bicycle battery is more suitable for use gel batteries. Resistant gel batteries discharge capacity and capacity was kept extremely strong electric avoid the impact on the battery discharge, and loss of water caused by the battery thermal runaway phenomenon.
Charging characteristics of lead-acid batteries of various brands are basically the same, but because the manufacturers of the battery material formulation, the electrolyte concentration and quality were different, the charging voltage also have some differences, therefore, strictly speaking, should be based on each battery manufacturing plant Specific requirements for determining battery charge voltage scheme, or likely to cause undue battery.
Electric Bicycles motor output power to match the battery's rated power, so in order to prolong battery life, the electric bicycle motor power to try to be less than the rated power of the battery to avoid battery long-term work at full load or overload conditions
