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 costs and reduce the total cost of ownership.

Lighter Weight: About 40% of the weight of a comparable lead-acid battery. A “drop-in” replacement for a lead-acid battery.
Easy Maintenance: Efficient maintenance with SOC and SOH monitoring.
Higher Power: Delivers twice the power of the lead-acid battery, even high discharge rate, while maintaining high energy capacity.
Wider Temperature Range: -20 ºC ~ 60 ºC

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).
