Thanks all, enlightening, Daydreamer and Mainesail. I do have the original from Hunter xantrax freedom 20 which book states that it has a 20amp charger and 2000w inverter. Is it 20 amps or 100 amps as stated by others? Best I can tell these boats came with one 4d agm... the other 2 were either options or additions but all three are professionally installed. Artboas..what 6v AGM's did you choose? Also I have a email sent to Marine How to about charger and house batts.?? Thanks, I am feeling better for a minute
I went with East Penn AGMs. They are wonderful!!!!
I highly, and thoroughly suggest you go with 6v batteries. And for engine start, a deep cycle 12v. M
Many years ago, I was a Xantrex owner. I had such awful customer support, I swore I’d never go back.
Go through these posts, and everyone will tell you that their experiences with Magnum Energy are first rate.
I would suggest the 2812. You could get by with one level down, but it’s not worth the saving. It’s a set & forget system.
When you install it, call Magnum for setup support. They are a pleasure to deal with.
Good luck!
