12V 50Ah Lithium Battery

12V 50Ah Lithium Battery
Product Details

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 : -20℃~60℃

●Superior Safety: Lithium Iron Phosphate chemistry eleminates the risk of explosion or combustion due to high impact 

   overcharging or short circuit situation


Applications :

●Solar and wind energy storage system 

●EPS and UPS battery backup 

●Signal system , emergency lighting system , security system

●Telecommunication Equipment 

●Golf trolleys & buggies ,wheelchairs ,scooters, electric bikes
