Features of LiFePO4 Battery
?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 power of lead acid battery, even high discharge rate, while maintaining high energy capacity.
?Wider Temperature Range: -20 C~60 C.
?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 four batteries in series and up to ten batteries in parallel.

Application
