I made a crappy ghetto box for my old depthfinder. It used those small 12v lantern battery.




LOL, but it worked. But with new equipment, I'm hoping to make things look a bit nicer and cleaner.:dj:
I need something that I can open up quickly and disconnect the battery. No need for a switch. Just a small hole for the power wires.
Measurements for the battery is 4"H x 6"L X 2-1/2"W
