12 Volt 50 Amp hour lithium iron phosphate battery 19 lbs
12V 50AH lithium iron phosphate pack 19 lbs
12V 4.5AH Lithium Iron Phosphate lead acid replacement

4.5 AH battery which can source up to 22 amps. Suitable lanterns, security systems, bicycle lights

These li-ion cells and batteries not only have high capacity, but can deliver high power. High-power lithium iron phosphate batteries are now a reality. They can be used as storage cells or power sources.

LiFeP batteries are among the longest lived batteries ever developed. Test data in the laboratory show up to 2000 charge/discharge cycles. Our cells typically have more than 1000 cycles in service.

These batteries are excellent for use in seasonal equipment because they do not need maintenance during the off-season. There is no equivalent to sulfation and the batteries can be stored in any state of charge without worry of degradation. We recommend 50-100% charge before storage. Another advantage is that running the battery completely down (i.e. leaving the lantern on for a week) will not damage the battery at all, unlike the SLA and Gel batteries.

NOTE: these can be connected in parallel to give more amp-hour capacity, but they cannot be connected in series to give higher voltage.
