fish finder and portable gel cell battery

[screwballl]

The fish finder mentioned, and most of these $70-130 models all have a low draw so you should be able to get an easy 12-24 hours of usage or more out of these small 5-10Ah batteries, and more than that on a 12V motorcycle, go kart, or other larger battery.

i picked this up to use on my float tube. it runs on rechargeable aa batts.you plug it in to the back like a normal battery. great on the boat, you can move it around.

Im thinking of getting another one (or two) of these gel cel batteries. I will need to power a humminbird piranhamax 170, front and rear lights, and a bilge pump. will one battery cover all, or should I get one battery for the fishfinder and another battery for the lights & bilge pump?

also, its been awhile since I put together a switch/fuse panel. is this the way to go ?
