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
monthes.
• 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.
