Phil,
The charge rate hardly is an issue. Yes a single Li will recharge faster. But very few of us have only 100 amp-hours.
How many inverter/chargers can do more than 127 amps of charging? I don't know of any at all.
My plans are for 400 to 600 amp-hours of SiO2. 400 may draw 100 amps of charging, and 600 would be 150 amps. So a 400 amp-hour li bank would only charge about 20% faster than SiO2.

The SIO2's dont look much better stat wise then a agm and way more expensive.
Then find me a battery that can be charged at -40 and can also survive being discharged totally 620 times before it degrades to 80% of OEM capacity?
Cycle life cost is cheaper than AGM.

This subject is new to me. I am missing something here ?
During cold weather, between 0-32F, it would be necessary to preheat a Lithium battery before my solar panel starts to charge it. Correct ?
Therefore, if I have my rv stored or parked in my driveway for days or weeks, I can't just forget about it like I do using my AGM batteries, correct ?
Using lithium's , I too was thinking about using an insulated battery box and install a heat pad in order for my solar to start charging it. Therefore, I really need to leave the rv plugged in to shore power in order to heat the pads.
The only real advantage for me to use lithium is for summer use when I could drop below 50% while boondocking and not worry about charging them back up on warm days.
If that's the case, using my AGM's in the winter and lithium's in the summer seems to be a better option . Either that or look into the Si02 batts as suggested. Am I correct on my thinking ?
