Solar with Lithium Battery
I will be purchasing a Battle Born lithium battery in a month or so. My truck camper came with a solar charge controller, inverter and I can simply drop the new battery in place of the lead acid one b...

Here is some honest advertising by Relion LFP
"More Usable Capacity 25-50% more capacity than lead-acid equivalent"
The OP wants to camp off grid in a TC for a few days where he runs a few things but not the furnace or bigger inverter loads, so he seems to think one 100AH battery will be enough as long as he has enough solar to keep up. With furnace and the usual things, it takes one battery per day.
He could do his loads with two FLAs and "enough" solar. He is hoping the one LFP will do it, being like 1 and 1/2 batts, which it might with no furnace time.
The money side of things is obvious and up to the OP for what is "worth it" .
EDIT--"enough solar" is the same for either battery bank size. IMO he will need 200w or more and 100w is not enough. On my budget, YMMV, I would get more solar with the money I saved from getting FLA instead of LFP. But I am not the OP!
I do most of my camping in the warm weather months here in Colorado off grid. The furnace has run twice in my Lance 650. I have used a space heater that works more than sufficient in 20 degrees hooked to 30 Amp.
The lead acid battery dies after about 2 days with the 100 watt solar panel. I'm probably not the best steward of making sure the battery amperage and usage stays moderated.
Maybe it's just marketing. I have read that lithium batteries charge faster than lead acid. I also know you can take the lithium batteries down below 50% capacity.
I thought maybe someone was using a 100 watt solar panel and 100 Ah Lithium battery and knew how long/much it would run before needing to run a generator if at all.
