Battery question for you trollers

[M R Dux]

G,
I thinks this is what he has in mind,

That was my plan on them. Looks confusing as all get-out, doesn't it? I have easy access to all 4 batteries so I may just wire in the back-up set to the Terrova once the main set gives up the ghost.

Weather for Saturday looks iffy and my wife is not comfortable out there in rough water and KY Lake can look like the ocean when the wind gets up. We have the chance to weigh in early if the fish cooperate or the weather gets nasty. Got to keep her happy. She did get a new fancy rain suit for the tourney.

Thanks for the input.
