This high-performance 20kWh (51.2V) Lithium Iron Phosphate (LiFePO4) battery delivers reliable, long-lasting energy storage. Engineered for safety and durability, it features the inherent stability and thermal safety of LiFePO4 chemistry. With a typical lifespan exceeding 2000 cycles, it offers excellent value and low total cost of ownership.
Its standard 51.2V nominal voltage ensures seamless integration with compatible inverters and energy management systems. Ideal for residential and light commercial solar energy storage, backup power systems, and off-grid applications.
Key Features :
♦Wall type: Easy connection, support max 8 set parallel connection.
♦Longer Cycle Life : Offers up to 5000 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
