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...

Yeah going with the LifePO4 battery cells has worked out really good.
I went with the EVITE 3.2v Grade A 280ahr cells and just connected up two cells parallel x 4 and it gave me a total air of 560ahr's. By connecting these up this way I was able to use a single 200a BMS to monitor and charge the cells, even bluetooth's to my phone so I can check state at a glance if needed.
.
Already had #1 wiring going from battery compartment to the generator compartment via a shut-off switch located there for future as I didn't order my camper with the Kohler genset for( 4k) but just the prep package which was no charge.
I then purchased my own 2200w dual fuel generator for $650 only drawback is I have to remove it from the compartment to run it.
Even had room in the rear of the compartment to install the 3kw inverter and I can switch to either source when I choose.
Actually saved about 40lbs in weight savings over the the original set. Also wanted to keep the battery's in the same location so that limited me to either Lead/Acid, Lithium, or the type I ended up going with.
Having all that reserve capacity is really nice to have.
