Anyone using Lithium batteries? Comments?

Update: Ok, my brother installed the BattleBorn batteries (2) 100ahs and upgraded chargers (house and alternator) as well as a 3000wt inverter. We wired microwave directly to inverter so I don’t have to use generator. Well, currently on Cape Lookout, NC for a 12-day fishing trip. What a FANTASTIC UPGRADE!! Voltage system starts at 13.6 and I’ve been here 2 days and have left the TV on for 12 hours each day, used microwave, lights and refrigerator and volts are now at 13.1.....haven’t had to run engine or generator at all. House lights are LED’s and are so much brighter. If you do any boondocking, this setup is worth every penny!! And, no it’s wasn’t cheap $2650 but a big investment for my type of off the grid camping. And I don’t watch TV for 12 hours....just testing the capacity of this system ??

I’ll follow up as the trip continues.
