Anyone using Lithium batteries? Comments?

Looking at upgrading to Battleborn Lithium batteries with charger/inverter for superior boondocking. Tired of running generator/engine to recharge the 2-Optima blue AGM batteries in use now. According to Battleborn, this will be far superior than what I'm used to seeing in terms of consumption and the daily charging cycle. I use a Dish satellite for TV, lights, furnace, frig, toaster, coffee maker, etc. With their system, I could also run the microwave without using the generator.

Anyone out there have first-hand experience with Lithium?
  • There are some top end manufacturers/retailers that offer models that can be charged down to -4F/-20C without damage, by borrowing some of the charging current, and self heating the batteries. Both Relion and LifeBlue make such a battery. There may be others.
    I have 2 X 100 Ah Relion RB100-LT batteries (charged by 3 X 100W ZAMP panels off grid) and so far so good. We don't worry about running out of power any more.
  • Plenty here do. I've been using 6 of them since last year, very happy with the setup, but you will need solar if you want to avoid generator - you can safely draw down the batteries to 90% (I don't go beyond 80%), but they need feeding. For the microwave, you will need a solid inverter and beefy wiring.
    I started a separate thread on cold weather charging of LifePO4 batteries. I built an insulated box (R10 styrofoam), with a waste tank heating pad and aluminum plate under the batteries to keep them warm. I also added a Victron temperature sensor to my equipment so that the MPPTs will not attempt to charge below 5C. Discharging is not the issue, they cannot be charged below 0C or you will damage them.
  • I am thinking of going the same route when my AGM's are done. I do use my rv all year round and that includes cold temps below 32F. 0-32F I'm on the fence as of now.
    If you are interested , there is a good comparison on YouTube for cold temp camping.
