Product Description

Key Features :
♦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 : -20ºC~60ºC
♦Superior Safety: Lithium Iron Phosphate chemistry eleminates the risk of explosion or combustion due to high impact overcharging or short circuit situation 

Applications :
♦Wheelchairs and scooters 
♦Solar/wind energy storage 
♦Back-up power for small UPS
♦Golf trolleys&buggies
♦Electric bikes
