When the batteries are used in series, if the internal resistance of the batteries is inconsistent, the battery terminal voltage during the charging and discharging process will be inconsistent. This will eventually cause the entire battery pack to be undercharged and fail prematurely. Therefore, the uniformity of the battery pack has a considerable impact on the service life of the battery.

For consumers, it is necessary to learn how to use batteries reasonably. This will also have a certain impact on the balance and consistency of the battery, thereby affecting the service life of the battery. Based on years of research and actual use of batteries, it is recommended that consumers use the following methods to reasonably use batteries.

1. Electric bike riding speed: 20-25km/h.
2. Riding distance: 10-30km/day, the depth of discharge is less than or equal to 70%. Perform a deep discharge every 2 months.
3. Charging frequency: once a day.
4. Load capacity: single rider, one child under 10 years old can be carried.

A better quality electric bicycle can be used for 3-5 years under normal use, and the battery can be used for about one and a half years. The shallower the battery discharge depth, the longer the cycle life of the battery, and the longer the battery life cycle. Therefore, consumers generally think that charging once is a cycle is wrong. If you want to extend the life of the battery you use, you must keep the battery in a fully charged state at all times. In the state of long-term power loss, the negative plate of the battery Very easy to salt. This will cause the loss of battery capacity and affect the battery life.
