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

Lithium 7.5 Amp Hour (AH) battery which can source up to 30 amps. Suitable for lanterns, security systems, and bicycle lights. One of the most popular SLA sizes!

These batteries have internal electronics to allow them to be used as a drop-in replacement for the equivalent sealed lead acid battery. They can be charged with lead acid chargers, and the 12.8 volt potential is very close to the 12.9V open circuit voltage of the lead acid chemistry.

To be even more cost-effective, 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 motorcycles, snowmobiles, jet skis, etc., (see application note below) 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 parking light on for a week) will not damage the battery at all, unlike the SLA and Gel batteries, since it has a low-voltage disconnect circuit.

This LiFePO4 battery will replace the following sealed lead acid batteries  

** Application note: Starting small engines. This battery will source 30-40 amps during engine starting, which is over half a horsepower. This is plenty of power to start most small engines. HOWEVER we have found that this might not be enough to start some high compression engines, particularly motorcycle racing engines and even some lawn mower engines. Please verify the current you need before ordering, because we will charge you a 15% restocking fee plus shipping if you return it.


Thanks. I'm a photographer and I ordered one a while back and recelled a battery for a broncolor Mobil strobe. It's awesome- the normal SLA battery would last about a half day on a catalog shoot but the lithium lasted 3 full days and still wasn't low. I'll tell all my photographer friends about them.--John R
