Hi, My challenger has two 6 volt 75 amp hour batteries for the coach and I just added 4 - 6 volt 225 amp hour trojans t105. I have been told that having the two 75 amp hour batteries hooked up with the 225 amp hour ones will degrade the 225 amp hour ones and they won't charge correctly. They are all flooded batteries.

At some point I will replace the 75 amp hour ones but right now don't have another use for them. They not even a year old yet so I hate to just get rid of them but I don't want to hurt my new batteries.

Is there some way of doing this that will make use of the old batteries, and the XM1800 watt inverter as well, I will be replacing it too with a Aims 4000 watt pure sine.

Any advice will be greatly appreciated.
Thanks
Don
