Product Details
Yangtze solar rechargeable 250ah 12v lifepo4 lithium battery
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 eliminates 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
