I would say Intel-Charger. They make their models up to 80 amp charger and have four levels of charging. Have one, works great and no a/c ripple. Super filtered! It only charges as much as you use when plugged in and is really fast for quick charging using the generator.
I can't help you on the battery's but I have heard they are good ones. Good luck, Capt.Dan

billba, welcome to iRV2.com. Wea re glad to have you join us. Those of us that have the larger inverter/chargers are able to set the charge rate and voltage up in programming the inverters. Here are some links that will help you with the battery questions if you have any.

I am adding a short cut into the RV Systems and Appliances section so we can get more responses on your questions. Good luck and have a great summer.

the key is to make sure you get a charger that has an AGM setting. This usually means avoiding equalizing charges.

The intellipower folks have a charge wizard for AGM's but you need to ask for it.

Most of the better inverter chargers will have such settings.

Bryant, The Intel charger I have has auto charger built in so it somehow figures out what kind of battery's and also not to get them hot when charging. It also has a remote but not needed as this one does everything automatically. I have wet cells and it has not 'cocked' the battery's yet. The book that came with it says ok for gel and agm as well as wet cells. Now if I could find the book in this jungle of stuff, I could give the model number. Its a intell-power 9200. About $400.00.

Before you get a very high amp charger, make sure your coach's isolator/battery controller can handle a high amp rate. I put a 90A Iota charger into a 2002 Dolphin LX, only to find that the isolator relay was rated at 60A and the control board had a 50A breaker built in. Max charge rate I could put through the system was 50A - found that out the hard way the first time the batteries got low enough to draw a really serious amount of current. I started the generator after a couple days of boondocking and POP! goes the breaker. I had to wire in a bypass using a battery switch so I could bypass the control board when I needed the full charge capability.

Iota makes some excellent chargers too, and they also offer the charge wizard option.
