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)
Functions of Battery
● OVP,UVP,OTP,OCP,SCP.
● Self-management on charging and discharging,single cell balancing function.
● Supports communication with equipment over RS485.
