type of powers/stem is a special backup power system The complete set of power system is composed of 4 battery packs arranged in series,1 high-voltage compartment and 1 complete set of battery management system. The battery management system can fulfill acquisition and control of the information such as temperature, voltage, charge current and discharge current, etc, of the battery.
Longer Cycle Life: Offer up to 20 times longer cycle life and five times longer float/calendar life than lead acid battery,minimize replacement cost and reduce total cost of ownership. Lighter Weight: About 40% of the weight of a comparable lead acidbattery.
A'drop in'replacement for lead acid batteries.
Deliver Twice power of lead acid battery,even high discharge rate,while maintaining high energy capacity.
Wider Temperature Range:
-20-60 degree 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 andup toten batteries in parallel.
