It's probably worth specifying which manufacturers are now suggesting increased charge rates? Lifeline still lists the same (
click) and I contacted them a couple of weeks ago and they suggested the AGM profile, indicating their site lists the proper voltages and in fact, they don't recommend the wet cell profile.
I don't believe Newmar uses Lifeline (?) so maybe it doesn't apply. Nonetheless, at $1600/pop - I'm inclined to follow the advice of the battery manufacturer vs Newmar.
All that said, I don't have the ePlex, thus maybe this is a moot point.
Good info though, thanks!
