[QUOTE="srimes, post: 223930, member: 6924"] Hi yall, 1st post here. Not ready to ask about my boat yet but I have a couple of comments here: 1) Batteries in parellel should be the same: same brand/rating/age/etc. If not the stronger one will always try to charge the weaker one, and burn up juice in the process. If it doesn't perform as expected this is probably why, and when you replace them replace both at the same time. 2) Doubling your batteries should more than double your run time. Batteries have less capacity when drained faster. A 125 amp hour battery gets that rating at a 10 hour discharge rate. Run it down in 2 hours and you get much less out of it (maybe 1/2 the rating). So with the 2nd batt the drain on each is 1/2 what it was on the 1, so you'll get closer to the rated capacity of each. Your 2-3 hours should turn in to 6-10. [/QUOTE]
