Feature Of Deep Cycle Lithium 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℃~60℃
♦ Superior Safety: Lithium Iron Phosphate chemistry eliminates the risk of explosion or combustion due to high impact overcharging or short circuit situation
