I realize everyone on here has different electrical req's with how they camp. I don't fulltime and don't camp in the winter and have minimal electrical req's. I dry camp don't watch TV or play on the internet, so basically some lights, refer, WH, and water pump. He kept talking about real world experience and did 20 amp discharge test down running MV's to 8 amp tests and then concluded that LI was cheaper over the life cycle of battery usage. What I would have rather seen was low amp draws "real world" how I use my batteries and how long each battery would last. At $900/ battery for lithium and $90 for 6v flooded that is 10 times the cost. Will the LI's last 10 times longer to recover the initial cost?

The only advantage for you would be never ever having to buy a battery again. Like me, you may be dead before you manage 2800 cycles.

If I camped every weekend, and took the SiO2 that meet my needs to stone bone dead (claim 620 cycles), then I'd reach 80% of oem capacity in only 4340 weeks, or about 83 years.

But, the float life is about 16 to 18 years--and I'll be 89.

My needs are cold weather performance, and enough storage to run an O2 concentrator over night.

Your right. My 2 6v Sams club batteries which I paid $74 apiece 13 years ago are still going strong. I will be 74 in 1 hr so one more set would last me until at least 87. If I needed to buy another set at that age, I would consider that to be a high class problem to have.
