Camping 3 months with single 100Ah Lithium
Before I started ramblin' this summer, I replaced my two lead acid batteries with a single 100 Ah lithium. I also added a second solar panel to go from 125w to 225w. I was on the road almost fiv...

The general thinking is that the Li batteries can use all their power and lead batts can use about half. SO a 100ah Li batts gives you the same use as a 200 ah lead battery that should not be discharged past 50%.
All my devices that use Li batts can be fully discharged and charged back (one cycle) around 1,500 times. I think these big batteries have fewer cycles, but one cycle is a lot to do in one day and hard to do unless you run a furnace the whole time.
If a laptop runs the battery down in 3 hours you have big problems. Look at your little laptop battery and look at your big 100ah battery. Those little laptop batts can run a laptop for 6-8 hours or so, so, how are you running your camper battery low? not make sense....
Something else is draining it, or you are starting with a low camper battery to begin with.
The worry about recharging below 32 degrees is real, but in reality, if your batt is inside, then how often is it going to get below 32? Keep the rig warm and the batt where it can stay warm from the rig and then you can recharge. This will be different for everyone.
