I have a 10' jon boat that I do small creak fishing with just using my trolling motor. The large marine battery that I use on my other boat is just huge for this small craft. I've been looking for an alternative battery but don't do this type of fishing enough to spend hundreds of dollars on a small battery made for this aplication. I have been looking seriously into power wheel chair batteries, small and relitively inexpensive. Has anyone else seen this or done this. Input or any other suggestions would be great.
