I personally will not run AGMs, I put 3 in my bass boat and 2 months later they were all dead, lucky for me BPS took them back under warranty. 31 is better than a 27 due to a larger reserve capacity so if you can fit them that's the size to use. make sure your invertor and or external charger are designed to charge AGM batteries or at least that selection. I personally wont change from a maintenance free marine battery.
