When used batteries in series, inconsistent if the internal resistance of the battery, battery voltage during the charge/discharge process is inconsistent, this will eventually cause the entire set of batteries not charging and premature failure. On an electric bike, battery balancing consistency has a considerable effect on the service life of the battery. For the consumer, how to use, battery balancing consistency may also cause certain effects, thus affecting the life of the battery. Based on research and practical use of batteries for many years, advised consumers to rational use of the battery in the following ways.
(1) electric car ride speed: 20-25km/h.
(2) riding distance: 10-30km/day, discharge depth less than or equal to 70% (deep discharge once every 2 months).
(3) charging frequency: once per day.
(4) load: single ride (be able to carry a child under 10 years of age one).
According to the above methods, high quality electric bicycle in normal use 3-4 can be achieved, or even 5 years, and the battery can be used about 1.5 years. Battery discharge depths shallower, longer cycle life of the battery, the longer the battery life-cycle. Therefore, consumers generally agreed that at a time on a single charge cycle is wrong, to make use of extended battery life, one must always put batteries in a fully charged state, State for a long time, the negative pole of the battery plate of salt, resulting in the loss of battery capacity, affecting the life of the battery.
