Re: AGM Battery Upgrade and Charger
Rated at 105ah, with 2 you can roughly assume you have 100ah usable before you need to top them up fully. The ratings are done assuming you draw at a specific rate and, therefore, their capacity will differ if you draw more or less at a time. Your specific systems will dictate how sufficient. The point is that you don't really want to get below that or you will shorten the life of those expensive batts.
A battery monitor is also a great investment, of you don't already have one.

In the harsh marine environment, something is always in need of repair. Margaritas fix everything.
