  • Please use our smart charger to charge your pack. (The voltage of the pack must match the voltage of the charger)
    • Charging time = (1.5 x Ah of the pack)/ Amp charging current
  • If you DIY by yourself, you MUST install our PCB or your own PCB with the following feature:
    • 4.2V/cell over-charge protection
    • 2.5V/cell over-discharge protection
    • Max current over-drain protection
    • Short circuit protection.  
  • Please check here for battery packs which are made by 809797 cells
  • Fire Retardant Bag to reduce the chance of damage if caughting fire
