3U Lifepo4 Lithium Ion Battery 48V 50Ah 100Ah 48 volt lithium battery for Backup Power Solar Energy Storage Systems
3U Lifepo4 Lithium Ion Battery 48V 50Ah 100Ah 48 volt lithium battery for Backup Power Solar Energy Storage Systems
Higher discharge rate, faster charging and discharging When there is a need for backup power supply for a period of 10 hours or less, we could reduce up to 50% of the capacity configuration, comparing to lead acid battery.
High security. Our lithium battery is safe, electrochemical materials are stable, no fire or explosion under extreme conditions such as high temperature, short circuit, drop impact, piercing, etc
Energy density is high. The volume and weight of lithium battery is 1/3 to 1/4 of the traditional lead acid battery with the same capacity.
Energy conversion rate is 15% higher than that of a traditional lead acid battery, the advantage of energy saving is obvious. Self-discharge rate < 2% per month.
Broad temperature adaptability. Products perform well at a temperature of -20°C to 60°C, without air conditioning system.
Cycle durability for a single cell is 2000 cycles 100% DOD, which is 3 to 4 times more than the cycle durability of a traditional lead acid battery.
