• LiFePO4 Lithium Battery

Description

Battery - Characteristics

  1. Better Cycle Life: Provides up to 15 times the cycle life and 5 times longer floating/storage life than lead-acid batteries
  2. Lighter weight: about 40% of the weight of an equivalent capacity lead-acid battery, saving up to 60% of the weight
  3. Fast charging: Short charging time compared to lead-acid batteries
  4. Low self-discharge: Compared to lead-acid batteries, the self-discharge is lower and can be stored longer without recharging
  5. Superior safety: Built-in multiple protection methods to protect the battery from overcharge, overdischarge, and short-circuit conditions
  6. High efficiency: The average round-trip efficiency (92%) is higher than that of lead-acid batteries (80%) (from 100% discharge to 0% and recharge to 100%)

Application Area:

  • Office and Public Facilities, Household Appliances, Network Transmission Equipment, Manufacturing, Control System, Solar Energy System, Oil Field, Drilling Field Operation etc.
  • Provide Stable, Reliable and Safe Power Solutions for Families, Islands, Ships and Other Small Photovoltaic Power Systems
