Piranha, I use another plug half on my charger. The battery shown on that particular photo is on the charger. The connector for the fish finder is inside the hull of my kayak. I have three of these batteries set up this way. You just need to make sure that the pins and sockets are aligned the same as far as the pin or socket side of the plug being on the positive or negative side of the circuit. That way they all mach up to the fish finder, bait tank or charger. I ended up re soldering a few connections for not paying attention to that small detail. You can convert any 12 volt charger to charge these batteries and you can dunk this set up without any problems. Here are a couple pix of the way the fish finder is mounted on my kayak with the wires running through the footwell bulkhead.
