However the smaller they are in amp hours, the less time you will have for trolling. General rule of the thumb is get the biggest (amp hour) that will fit and you can afford. You never know when the fish will turn on big time and you just don't want to have to quit because you run out of trolling power. Also remember the most important things you can do to prolong their life is keep fluid levels up, keep connections clean and tight, and RECHARGE ASAP after EVERY use.
AMEN and AMEN.
