And plop that in one of those Plano boxes.



This is pretty much what I have. It's a 15Ah battery, that's very small and lightweight. Lasts multiple days as well. Drilled a hole for the cable output, and gooped it for a watertight seal.

very interesting, and you are powering your GPS with this I presume. Did you splice the DC power cable ?

Yup, I power a Dragonfly 5.7" which has GPS as well. Max power at full brightness draws a max current of 0.83A, and the battery has a max output current of 2A at 12V.

Yea, I just spliced in these:http://www.kayakfishingsupplies.com/...-pin-connector



One end connects to the DC output cable (I also added in a in-line fuse), and that connector part sticks out of the plano box. Other connector goes directly to the power cabling of the fishfinder.

Looks like this (not exactly mine, but I based mine off of this):
