Product details

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. 

● Intelligent design,supports battery upgrade over RS232. 

● Colorful LCD,displays battery information

Qualifications

● 20 years professional experience on lithium ion battery  power designing, manufacturing, sales

● Passed ISO9001, ISO14001, ISO45001, UL1642, CE, ROHS, IEC62619, IEC62620, UN38.3

● Battery cell cost advantage
