I have a 1995 60 HP mercury engine. I have recently purchased a Xi5 pinpoint trolling motor. I use the anchoring mode quite a bit with my Lowrance HDS 7 gen 3 fish finder. It uses nearly all of my battery AH for a whole day.I don't know the max output of the alternator (does anyone know?).Am I taking a chance of damage tomy engine alternator (it now charges only my engine start battery) if I alsoconnect to it to trolling battery? Would I be better off getting another battery & parallel them. I am thinking about getting a solar panel to charge them as I may not have access to power. Thanks in advance for any help
