Selection of batteries for electric bicycles


AGM battery has the advantages of low cost, large discharge current advantages, but there is a temperature range is narrow, cell defect dehydration and thermal runaway; GEL battery has high cost, but it has stable performance, wide working temperature, anti overcharge over discharge and long life etc..
As the electric bicycle batteries are mostly high current and deep cycle discharge in most cases, the battery of electric bicycle is more suitable for the use of gel batteries. The colloid battery has the extremely strong over discharge ability and the strong electric liquid preservation ability, avoids the influence of the over discharge to the battery, and causes the thermal runaway phenomenon because of the battery losing water.
Charging characteristics of lead-acid batteries of various brands are basically the same, but because the battery material formulation, the manufacturers of electrolyte concentration and content were different, the charging voltage also have some differences, therefore, strictly speaking, should according to the specific requirements of each battery manufacturers to determined the charging voltage of the battery, otherwise easy to use the cell caused by the improper.
The output power of electric bicycle motor to the rated power and battery matching, thus to extend the service life of the battery, the rated power of motor power of electric bicycle to try to avoid less than the battery, the battery work in full load or overload conditions over a long period of time.
