Motive Lithium Battery

Lithium Iron Phosphate Battery LP20-4820 (51.2V/20Ah)

MUST’s robust Lithium ion phosphate batteries are the best choice for a long-lasting, safe, eco-friendly energy solution. They are your best choice for your golf trolley, plus light weight & compact size, those batteries make your golf trolley able to go far distance at a higher speed compared to traditional Lead Acid Batteries.

Features:

  • 1500 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.
