51.2V 100Ah LiFePO4 Battery Pack for solar system


51.2V 100Ah LiFePO4 battery features:
  • High cycle life: 4000 cycles @80% DoD for effectively lower total of ownership cost
  • Longer service life: low maintenance batteries with stable chemistry.
  • Built in circuit protection: Battery Management System (BMS) is incorporated against abuse.
  • Better storage: up to 6 months thanks to its extremely low self discharge (LSD) rate and no risk of sulphation.
  • Quickly recharge: save time and increase productivity with less down time thanks to superior charge/discharge efficiency.
  • Extreme heat tolerance: suitable for use in a wider range of applications where ambient temperature is unusually high: up to +60°C.
  • Lightweight: lithium batteries provide more Wh/Kg while also being up to 1/3 the weight of its SLA equivalent.
