LiFePO4 Battery Charging Guide:

  • NEVER charge LiFePO4 batteries with a charger not specifically compatible with LiFePO4 batteries!
  • When the cell is first used, it MUST be fully charged and discharged for activating it and giving fully capacity.
  • Always charge LiFePo4 batteries in an area with adequate ventilation.
  • No matter what charge mode the battery is in, stop charging once the cell temperature exceeds the absolute charge temperature range.
  • No matter what charge mode the battery is in, stop charging once the cell voltage exceeds the absolute charge voltage.
  • When the LiFePO4 batteries are intended to be stored for a prolonged period of time (more than one month), the SOC of cells should be adjusted to around 50% periodically(every three months is recommended).


1. One cell will come with one set busbar, bolt, and washer for free. (e.g. 4 Cells will come with 4 pcs(busbars + bolts + washers) .
2. Each cell shall be used under the strict monitor, control, and protection by the BMS.
3. Before the first use, always charge the cells to full voltage.
4. The battery is suitable for DIY lovers with experience.
