The Sun Fun Kits Heated Battery Jacket is the ultimate cold weather solution! Add active heating to any lithium battery enabling year round use, works with batteries that have internal heaters as well as those that have only low temperature cut-off. The SFK-HJ works with 12v batteries (or 13.6-14.4v lithium batteries) however you can still connect your batteries in series connection (such as if are using a 48v bank) as the battery jacket uses the 12v terminals of the battery itself.


The jacket also provides excellent environmental protection as its constructed out of heavy duty 1680DN water proof nylon fabric which will keep you battery safe from environmental elements such as: dust, debri, common rv fluids, and also provides excellent moisture resistence. The jacket has 2 wire entrance holes which can support up to 4/0 cable.
