Absolutely!

Thanks for that clarification. I was reading "LiPo" and thinking "polonium?! Can't be."

The battery system used by the Mortons in the OP video works out to about 433Amp-Hours (200+ usable amp-hours) in a battery pack that weighs 55 lbs.

The equivalent lead acid battery system would require about six GC2 6V batteries weighing approx. 400 lbs.

So, on a weight basis (which all owners of small light trailers are concerned) its about 7 TIMES weight factor.

As for using propane for cooking (non-renewable), it reduces your boondocking time. If you cook with electric induction cooktop/Instant Pot/Convection oven/microwave off a solar charged battery system (renewable and green), as far as propane is concerned, you can avoid town indefinitely. One less limitation.

Actually, I think it's better than that. I believe with lithium batteries, you can discharge up to 80% with no problems. That said, with 433 total amp-hours, you're closer to 350 usable amp-hours.

From what I've seen, boondocking forays aren't usually limited by power or propane, or food for that matter. It's the tanks that get ya. And it's not the fresh water tank either. You can always bring extra Jerry cans. It's the grey/black tanks that force people back to civilization.

As for Lithium, I'm trying to rationalize the extra up-front cost. For roughly 3x the price of AGM you get longer life (I think I read 2-3x somewhere) . Because they discharge deeper you get roughly twice the usable amp hours, which translates into half the weight and space. On the downside, they can't handle really cold temperatures and they can't accept a charge below freezing, forcing you to store them inside the unit and maybe taking them out of the unit in the winter time. That can be a deal breaker in some areas.
