Features of LiFePO4 battery
  • Longer Cycle Life: Offers up to 20times longer cycle life and five times longer float /calendar life than lead acid battery.
  • Lighter Weight: About 40% of the weight of a comparable lead acid battery. A 'drop in' replacement for lead acid batteries.
  • Higher Power: Delivers twice power of lead acid battery ,even high discharge rate, while maintaining high energy capacity.
  • Superior Safety: Lithium Iron Phosphate chemistry eliminates the risk of explosion or combustion due to high impact, overcharging or short circuit situation.
  • Increased Flexibility: Modular Design enables deployment of up to up to ten battery in parallel.
