Lithium Batteries for Solar Off Grid
Description
Technical Parameters
Feature of LiFePO4 Battery Product Photo
● 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 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 battery.
● Higher Power: Delivers twice power of lead acid battery, even high discharge rate, while maintain high energy capacity.
● Wider Temperature Range: -10℃~60℃
● Superior Safety: Lithium iron phosphate chemistry eliminates the risk of explosion or combustion due to high impact,over charging or short circuit situation.
● HW12100 S
● No Memory Effect: Support unstable partial state of charge (UPSOC) (charge/discharge) utilization.
