About 40% of the weight of a comparable lead acid battery,A "drop in" replacement for lead acid 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.
