Longer Cycle Life: Offers up to 20 times longer cycle life and fiveimes longer float/calendar life than lead acid battery, helping tominimize replacement cost and reduce total cost of ownership.

Lighter Weight: About 40% of the weight of a comparable leadacid battery.A'drop in' replacement for lead acid batteries.

Higher Power: Delivers twice power of lead acid battery, evenhigh discharge rate, while maintaining high energy capacity.

Wider Temperature Range:-20C~60C.

Superior Safety: Lithium lron Phosphate chemistry eliminateshe risk of explosion or combustion due to high impact, overchargincor short circuit situation.

Increased Flexibility: Modular design enables deployment to four batteries in series and up to ten batteries in parallel.
