Lithium Iron Phosphate ECO ESS Battery
energy storage battery with building block design and flexible power capacity config.
Lithium Iron Phosphate ECO ESS Battery LFP12.8-250(12.8V250Ah)
- Longer Cycle Life: Offers up to 20 times longer cycle life and five 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 batteries.
- Higher Power: Delivers twice the power of lead-acid battery, even higher discharge, while maintaining high energy capacity.
- Wider Temperature Range: -20C° ~ 60C°
- Superior safety: lithium Iron Phosphate chemistry eliminates the risk of explosion or combustion due to high impact, overcharging or short circuit situations.
- Increased Flexibility: Modular design enables deployment of up to four batteries in series and up to ten batteries in parallel.
