I use an independent adjustable power supply, because after reading on here for months, and establishing who know what they are talking about, and can walk the walk after talking talk, I listened to reason.
It helps that I was a battery buster/tester/installer for Sears Roebuck while going to school, and saw a lot of wrecked batteries and good batteries, as well as tested them for failure.
You'd be hard pressed to not follow a recommendation by a former battery failure engineer here for one of the biggest commercial golf car and sweeper industrial battery makers that sell here in the USA. I'm talking about MexicoWanderer. Until he goes senile, you can take what he posts on the subject matter, with the common sense and test of reasonableness, to the bank.
15.0V while dry camping works for me.... daily... though YMMV. 14.4V might be good for you and your AGM batteries. 15.3 might be good if you own US brand batteries in a Group 29 or Group 31. Applications and V necessary vary by brand, materials and construction. See what your manufacturer recommends is the best you can do. This is why it is so foolish to mix sizes, types and brands of batteries, they all have varying requirements.
