What to pay attention to when charging and discharging polymer lithium ion batteries

The charging current and charging voltage of the polymer lithium battery must not exceed the following standards. If they exceed the specified value, it may cause damage to the charging and discharging performance, mechanical performance and safety of the battery, and may cause heat and leakage. 2. The discharge current of the discharging polymer lithium battery shall not exceed the following standards, and the discharge must be carried out within the scope of this standard. The discharge current of single battery must be less than 2C5A; the temperature range of polymer lithium battery is -20~+60℃ when discharging; the final discharge voltage of single battery is not less than 2.75V. 3. Over-discharge It should be noted that during the long-term unused period of polymer lithium battery, it may use its self-discharge characteristics to be in a certain over-discharge state. In order to guard against the occurrence of over-discharge, the battery cell should be charged regularly to maintain its voltage above 3.0V. Over-discharge will cause loss of cell performance and battery function. It is required to add qualified lithium battery protection circuit board for detailed use.
