Polymer battery pack

Charging Battery Use only approved chargers and procedures. Improperly charging a cell or battery may cause the cell or battery to flame or damage. Charge the battery using the “CCCV” or constant current /constant voltage method. Do not charge the battery with a current or voltage higher than the specified maximum value in this specifications. The absolute maximum charging voltage is 4.25V per cell. Prohibit reverse charging of the battery. The battery must be connected correctly. Discharging Battery Discharge battery at the max current specified in this specification. If you plan to discharge battery at a higher current than the max current, please consult GBP. Avoid discharge the battery below 2.75V for each cell. Do not over-discharge the battery. Over-discharging can damage the performance of the battery. It should be noted that the cell/battery would be at an over-discharged state by its self-discharge characteristics in case the cell is not used for long time. In order to prevent over-discharging, the cell/battery shall be charged periodically to maintain between 3.7V and 4.1V.
