They dont not offer support on their products

Please do not buy from these guys, their batteries are absolutely trash, i bought a 100ah lithium battery and the battery barely gives me 20 - 30 ah, i was better off with my 4 deep cycles, and now they are telling me they don't make the batteries and therefore its not their problem, do yourself a favor a spend a little more and get a proper battery from a reputable place, these guys have the worse customer service out of any business that I've ever dealt with.
