Lithium Battery

@jato, your timing couldn't be better as LiFePO4 batteries are at a price point that makes the decision a no brainer. If it were me, I would look at a 200amp hour battery with a BMS(battery management system) and internal heater that will protect it in cold weather. LiTime and BattleBorn are the favorites on the Escape forum. The 200amp hour battery will have a slightly larger footprint but give you the ability to add an inverter later if you choose.

So, the battery can come first, then a controller to better manage it? I had only the controller-then-battery sequencing, but this gives me the opportunity to start shopping for a battery before I’ve torn into my existing electronics.

Thank you men for your advice, much to ponder and think upon.  At the moment I still lean to the 100 aH lithium.  Why?  Cost is one, as previously mentioned in other posts my cost in the past 15 years for batteries is $22/year, quite conservative.  If I go "big" and spend $500+ or more for bigger battery and newer converter, that cost will rise dramatically.  Also, when camping, I don't spend more than 1 week of grid at one location, so as long as I can go that long, I don't see the need for more aH.  As it was with my lead acids, I could go 6 days at a time when night temps were in the 40's; with the furnace eating up the bulk of those amp hours.  Also, I don't utilize either solar or generator, it's basic camping.

I really dislike the AH rating they apply to batteries because it does not indicate how much power they are storing. I much prefer Watt-hours (WH) rating that factors in how much you can discharge them.

Originally posted by jato Thanks GG!  So the info on my Trojan T-1275 is rated at 160 aH.  Does that gives me about 960 WH usable storage?  Is that correct?  Good to know that lithium you gave as an example provides 1200 WH of usable storage.  I am liking this a lot.
