NPFJ050X10 72V 50Ah Lithium battery

NPFJ050X10 72V 50Ah Lithium battery

Overview

  • Longer Cycle Life: Offers up to 15 times longer cycle life and 5 times longer float/calendar life than lead acid battery.
  • Lighter Weight: About 40% weight of a comparable lead acid battery, save up to 60% in weight.
  • Quick Charge: Short charge time compared with lead acid battery.
  • Low Self-Discharge: Lower self-discharge compared with lead acid battery, longer storage time without recharging.
  • Superior Safety: Multi-protection methods built inside to protect the battery from overcharge, over discharge and short circuit situation.
  • High Efficient: Higher round-trip energy efficiency of the average (92%) than lead acid battery 80% (discharge from 100% to 0% and back to 100% charged).
  • Certifications:

    • ISO-9001 ISO-14001 Iso_45001 CE_marking_logo UN38.3-icon CQC
    Compliant to: IEC 62133-2
