1,Longer Cycle Life:Offers up to 20times longer life and five times longer fioat life than lead acid battery, helping to minimize replacement cost and reduce total cost of ownership.
2,Lighter Weight:About 40% of the weight of a comparable lead acid battery. A 'drop in' replacement for lead acid batteries.
3,Higher Power:Delivers twice power of lead acid battery,even high discharging rate,while maintaining high energy capacity.
4,wider Temperature Range:-20ºC-60ºC.
5,Superior Safety:Lithium Iron Phosphate chemistry eliminates the risk of explosion or combustion due to high impact,overcharging or short circuit situation.
6,Increased Flexibility:Modular design enables deployment of up to four batteries in series and up to batteries in parallel.
