Lithium Battery Charging System
It is time for a new battery in my '04 Lance 921. I am looking at an Interstate battery they sell up the road. But through my research into charging systems/problems, I got to thinking about Lithium...

Hello, hoping I could jump onto this thread to ask a topic related question.
I added a lithium LifePOE 100ah battery a little over a week ago to my 2000 Lance 820. I charged it before use for several days using a lithium charger as instructions recommend. The day before leaving for boondocking I hooked it up. Unfortunately, I reversed the positive/negative wires. After discovering my mistake, I hooked it up properly and appeared that everything worker ok.
The first night the new battery died.
I was able to jump start the onboard propane generator and it appeared to charge the lithium battery. After the sun set the battery died again.
After a several hours of sunlight (I have two wired roof top solar panels) the battery was charged enough to start up the generator without a jump.
Thinking the battery was bad I purchased a deep cycle interstate wet battery. After the first night of use it also drained dead. Again, after several hours of sunlight the battery was charged enough to start the generator.
In the evening I ran the generator before dark to charge up the battery for the night and the generator died apparently from the lack of electrical energy due to the sun now being unavailable.
So, everything works on shore power and when the battery is fully charged and when on the generator. But when using the generator alone without sunlight the generator dies and there is no electricity available.
I checked for any tripped or broken fused with negative results. It feels like the generator is draining the batteries.
Would anyone out there have any ideas what damage I might have done to the camper or where to begin trouble shooting?
Any help would be greatly appreciated.
I have the camper on a 2015 GMC 2500.
