Lithium Iron Phosphate (LiFePO4) Battery
12.8V, 32AH

Features of LiFePO4 Battery
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.
