Lead Acid Replacement

Lithium Iron Phosphate Battery LP15-24125 (25.6V/125Ah)

With smart design and elegant appearance, MUST LiFePO4 battery is an ideal replacement for traditional lead acid battery,offering a drop-in solution for lead acid battery replacement. Our battery can be used individually or assembled in series to create larger system.

Features:

  • 4000 cycles @80% DoD for effectively lower total of ownership cost;
  • Low maintenance batteries with stable chemistry;
  • Battery Management System (BMS) is incorporated against abuse;
  • up to 6 months thanks to its extremely low self discharge (LSD) rate and no risk of sulphation;
  • Save time and increase productivity with less down time thanks to superior charge/discharge efficiency;
  • Suitable for use in a wider range of applications where ambient temperature is unusually high: up to +60°C;
  • Lithium batteries provide more Wh/Kg while also being up to 1/3 the weight of its SLA equivalent.
