Thanks Guys - Looks like I have a project for after work today. ?

Neighbor was cleaning out his garage and just asked me if I had any use for a new marine battery selector switch. Thinking about using this to add a battery selector to my trolling motor. I have a 12v Minnkota 55lb motor and 2 x 12v batteries with a Minnkota 2 bank onboard charger. The batteries are in a compartment under the rod storage so its a bit of a pain to get at and swap the battery when one gets tired. Ive tried wiring both batteries in parallel, and even though they are similar capacity they never seem to get a full charge and take forever to charge like this so Ive kept the batteries separate. Thoughts on the attached wiring diagram - should work but I wonder about the common ground with charging.
