GBS LiFePO4 High Power battery pack 40Ah

Standard properties


  • High performance: The continuous discharge current standard is recommended between 0.3C to 1C.
  • The continuous maximum current is 3C.
  • The maximum impulse discharge current for <10 sec is at 10C.
  • The maximum charging current is 1C
  • Good performance at temperatures from +5 ° C to +40 ° C.
  • The battery structure is stable and safe
  • Good performances at low temperatures. The 100% discharge is defined at 20 ° C. At temperatures below 0 ° C, the discharge current power falls. Do not charge battery under 0 ° C.
  • Security: The battery can not explode or burn through internal or external damage.
  • Long life cycle: The capacity of the cells occurs after 5000 cycles at 80 % strength capacity utilization in the range of 80% of the initial capacity.
  • Adapted for fast charging: Within an hour, the battery can be charged to 85%. Fully charged after 2-3 hours
  • Low cost relative to performance / lifetime.
  • Battery does not contain polluting heavy metals
  • Battery is made with modern materials at state of the art

Safety instructions before using the battery


  • Preclude a short- circuit in battery
  • Charge battery fully before the first use.
  • The battery pack is secured with a clamping plate, please never remove the clamping plates while using.
  • Check the voltage of cells, it should range of 3.31 – 3.33 volts
  • Install the BMS according to our instructions to prevent overcharging and deep discharge.
  • Check if all parts are complete.
  • The installation should be carried out in accordance with the accompanying description.
  • The 4 screws should be connected to the silvered copper bridges.
  • A not intended application reduces life of your battery.

Care and Maintenance


  • The battery is permanently sealed (maintenance free)
  • Do not deform or puncture Battery mechanically. Do not short-circuiting Cathode and Anode. Please do not throw the battery into fire.
  • Do not connect different types of batteries with each other.
  • Do not connect cells of different capacity either in series or parallel.
  • Please store the battery in a dry and ventilated place. Please keep away from food, moisture, heat and fire.
  • Please charge the battery for more than 60% capacity before storing them longer. Check the voltage monthly. If it is below 3 volts per cell, the battery must be charged.
