48V 50Ah 2.4Kwh Server Rack LiFePO4 Battery Pack
This EVL 48V 50ah server rack lifepo4 battery is the perfect option for off-grid energy storage systems. We designed a brand new 48V 100AH LiFePO4 Battery pack with our high-quality 10Ah LiFePO4 single battery cells. They are an energy storage system for houses with a capacity of 2.5kwh. The 48V Lithium Battery bank with LiFePO4 technology meets the highest safety standards and has a super long life cycle, optimized with a proprietary manufacturing process and battery architecture. The state-of-the-art Battery Management System (BMS) provides comprehensive protection features and real-time monitoring.
Features of 48V 50Ah lifepo4 battery pack
● Longer Cycle Life: Offers up to 10 times longer cycle life and five times longer float/calendar life than a lead-acid battery. It is 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 a 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.
