Do not over-discharge or overcharge (most important!) When the battery reaches the cut-off voltage 10V, the discharge will stop. (need to charge in time) Charging stops when battery reaches 14.6V charging voltage. The battery always operates within a voltage range of 10V-14.6V (also known as full charge and full discharge). This can effectively extend the LiFePO4 battery life. 2. Maintain battery power. When the battery is not in use, it will maintain a certain amount of power. 3.Charge with standard current (4A) The large current charge does not affect the overall service life of the LiFePO4 battery, but the relatively slower charging speed can give the BMS enough time to balance the power of each battery cell, which is beneficial to extend the battery life with one use.
