have 2-12 volt batteries that are separated (one on each side of the boat) and was going to use a separate charger for each battery. was going to use a minnkota MK-106d single bank charger foe each battery. can't seem to find room for a duel bank charger and would have to run a long extention for one of the batteries. already have one MK-106d so the price saving is good. do I connect each charger as I would to a single battery?
