Cautions
- Charging current should not be more than maximum charge current specified in the Product
- Specification, Charging current bigger than recommended current may damage the battery;
- Discharging current should be no more than maximum discharge current specified in the Product
- Specification; Discharging current bigger than recommended discharge current may damage the
- battery;
- It should be noted that the cell would be possible to be at a 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 shall be charged periodically to maintain between 38.4V and40.8V
- (Recommended 3 months one cycle).Over-discharging may causes loss of cell performance,
- characteristics, or battery functions;
- Please charge the battery within 12 hours after use;
- Battery storage environment follow the above conditions and in standard atmosphere, should be
- without strong magnet, no power, no static;
- Do not reverse the polarity of the battery pack for any reason;
- Do not short circuit the battery pack;
- Do not reverse polarity charging;
- Battery packs can be combined in series or in parallel according to the specification;
- IP65. Do not immerse the battery pack in water or sea water;
- Do not disassemble battery;
- Do not expose the battery to extreme heat or flame;
- AGM charger or truck alternator is recommended. Excludes chargers with automotive
- rejuvenation function.
- Lithium-ion charger is acceptable.
