    Battery care and maintenance

    Please charge the battery timely after kept for more than 2 monthes so that the battery cycle life would be much
    longer. The cycle life of li-ion battery would be shorted if the battery alway be kept as fully charged state. For
    long time storage, keep the battery as 40~60% state of charge (SOC) and discharge and charge every one or two
    • Battery should be kept under dry and ventilation condition. Do not put the battery close to fire and explosive
    products. When charging the battery, cut of the load.
    • The best working environment of our lifepo4 battery is 15 ~ 40 °C, please take some necessary procedures, like
    heating & cooling system, or use heat insulation materials to stop cold effect battery in winter.
    • When the temperature is more than 75°C (Internal temperature of the battery), the battery cycle life would be
    shorted. So do not exposure the battery under the sun during summer.
    • When the temperature is under -20°C or lower, the battery performance would be effect and the mileage might
    be shorted.
    • Do not wash the battery shell with organic solvent. If there’s fire accident, please do not use CO2 to extinguish
    the fire but use CCl4 or sand soil.

    Battery Pack Installation & Maintenance (For Technical Refernece only)

    Please study the related datasheet and user manual before the installation of battery pack, BMS and Charger.
    • Fix the battery installation location and install the battery pack under ventilation cooling environment.
    • Please be careful and prevent the battery from short circuit.
    • All the cables should be the standard match that can resist the related temperature and voltage.
    • Please install/change the BMS under the instructions of operation manuals and make sure every part is rightly
    and tightly connected. BMS install requires the right sequence of parts, please be aware.
    • If the battery pack is separated, please pay attention to the connecting steps and composition way.
