Features of 48V Lithium LiFePO4 Battery Pack:

  • Longer Cycle Life: Offers up to 10 times longer cycle life and 5 times longer float/calendar life than lead acid battery. Helping to minimize replacement cost and reduce total cost of ownership.? Lighter Weight: About 40% of the weight of a comparable lead acid battery. A "drop in" replacement for lead acid battery.? Higher Power: Delivers twice power of lead acid battery, even high discharge rate, while maintain high energy capacity.? Wider Temperature Range: -20?~60?? Superior Safety: Lithium iron phosphate chemistry eliminates the risk of explosion or combustion due to high impact, over charging or short circuit situation.? No Memory Effect: Support unstable partial state of charge (UPSOC) (charge/discharge) utilization.

Functions of BMS:

  • Over charge detection function
  • Over discharge detection function
  • Over current detection function
  • Temperature protection function
  • Short circuit detection function
  • Balance function

Applications:

Electrical vehicles, Solar/wind energy storage system, UPS, backup power, Telecommunication, Medical equipment, Lighting, etc.
