When the battery is used in series, if the internal resistance of the battery is inconsistent, the battery voltage in the process of charging and discharging will be inconsistent, which will eventually cause the whole group of battery undercharge and premature failure. Therefore, in the electric bicycle, the uniformity of the battery pack on the battery life has a considerable impact. For consumers, how to use, will also have a certain impact on the balance of the battery, thus affecting the battery life. According to the battery over the years of research and practical use, it is recommended that consumers use the following methods to rational use of batteries.

(1) electric car riding speed: 20-25km / h.

(2) riding distance: 10-30km / day, the discharge depth of less than or equal to 70% (every 2 months for a deep discharge).

(3) Charging frequency: once a day.

(4) Weight: single riding (can carry a child under 10 years old).

According to the above method, the quality of electric bicycles with good use can be normal use can reach 3-4 years, or even 5 years, and the battery can use about a year and a half. The deeper the battery discharge depth, the longer the battery cycle life, the longer the battery life cycle. Therefore, consumers generally believe that the charge of a power cycle for the idea is wrong, in order to make their own battery life extension, it must always make the battery in a fully charged state, a long time under the state of power loss, the battery negative plate Easy to salinize, resulting in loss of battery capacity, affecting the battery life.
