Everyone is trying to compare lithium against flooded lead acid. Where are the comparisons to absorbed glass mat? It's easy to hawk the performance advantages of a Ferrari versus a checker cab. Let's snatch away the checker cab and replace it with a corvette.
I asked on this forum about the number of really serious boondocking campers. There are only a few. Three thousand discharge cycles equals one cycle a day for 8.219 years. Yeah, 365 days a year. Tip: If you think you need this I would not advise going into the area of financial management. BFL13 could conceivably dig into the abilities but he like me, should seek the Fountain of Youth because of the disparity of expected lifespans. Ninerbikes is another potential viable candidate. I am not. not even close.
Methinks I am looking at a toy for around 90% of RV'ers who boondock. The numbers do not crunch. Crunch hell, they don't even crack. "I've got LITHIUM" would make good around the campfire fodder but would actually be an admission of ill planning.
Four group 31 QUALITY AGM batteries is enough inverter food to have an eleven hundred watt inverter jump out the window. Like I mentioned before NONE OF YOU have a generator big enough to even meet a fraction of the charge acceptance of 400 ampere hours of lithium. Couple an old reliable NHC 6.5 generator with 400 amps and you have a STALL.
Time to fall back five and punt. You may lust for the technology but like Mountain Gorilla hide boots, validating their cost and attributes would take a whole heap of justifications that upon examination, falls flat on it's face...
