Advantage:

Longer cycle life: Offers up to 20 times longer cycle life and fivetimes 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: -20 C~60 C.
Superior safety: Lithium iron phosphate chemistry eliminates ,the risk of explosion or combustion due to high impact, overchargingor short circuit situation.
Increased flexibility: Modular design enables deployment of upto four batteries in series and up to ten batteries in parallel.
