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...

I ended up building my own LifePO4 set-up myself.
Went from 98ahr's to 560ahr's.
Already had 510w of solar on roof and a 30a charge controller that was compatible. Changed out my 120v on-board charger ( have yet to even use ). Also added a Victron DC/DC 18a isolated charger to top off when driving down the road and never have to worry.
Also added a 3000w inverter that we use for the coffee maker in the AM and occasional microwave use and haven't used my generator since going this route.
Probably set me back 2.5k total but should last quite a while.
With the storage capacity I have now I don't even charge everyday.
Not a cheap way to go but I know it will last and it's installed correctly.
Retired IBEW Contractor here in SD so I gots the skills.
Good luck.
Sounds like a very sweet set-up you’ve got Sir :) !!
(FWIW, very similar to my 400a/h LFP supported by 660w rooftop truck camper solar…)
