Alot of us have really powerful and expensive fishfinders. Why cheap out on the power source? Having that extra capacity in a smaller lighter package that will probably outlast your kayak is worth it in my opinion.

There ya go, just put it/them in a waterproof container with a top (take top off to charge), drill a small hole in box to run wires through and 5200 them in place, a few waterproof connectors, and your in business. Like any battery, anything that causes a very fast discharge, like submersion, will create an electric thermo transfer, i.e., heat, enough to create a fire, or melt a yak. The nice thing is that a 20amph LION is about the size of a cigarette box.
