I keep mine plugged into an onboard charger to charge the batteries but it is an aluminum boat I recently learned about "electrolysis" and wondered in this was really necessary?
Also, since the TM battery (only one right now) is only for the TM, is the starting battery the only battery that would need the cut off or would you want to shut off both if you did need the switch?
