Features of LiFePO4 Battery
● 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℃~55℃.
● Superior Safety: Lithium iron phosphate chemistry eliminates the risk of explosion or combustion due to high
impact,over charging or short circuit situation.
● No Memory Effect: Support unstable partial state of charge(UPSOC) (charge/discharge) utilization.
