48V 50ah 100Ah 200Ah Server Rack LiFePO4 Battery
48V 50ah 100Ah 200Ah Server Rack LiFePO4 Battery for home energy storage
EVL 48V 50Ah/100ah/200Ah Server Rack LiFePO4 Battery Pack For Home Energy Storage
48V lifepo4 batteries Features
● Longer Cycle Life: Offers up to 10 times longer cycle life and 5 times longer float/calendar life than lead acid battery. Helping to minimize replacement costs and reduce the total cost of ownership.
● Lighter Weight: About 40% of the weight of a comparable lead acid battery. A ” drop-in” replacement for lead acid battery.
● Higher Power: Delivers twice the power of the 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 situations.
● No Memory Effect: Support unstable partial state of charge (UPSOC) (charge/discharge) utilization.
