My 675 ampHr AGM bank cost me $350
That's a long ways from the $4200 needed for an equivalent lithium bank
Maybe a portion of a converted salvaged Prius bank, for the right price, $1000 or less
I used what outwest said he has (800AH AGM; 4 (6) volt Fullriver DC-400-6s) internet price when I quickly searched was $500+/- each. Which would be 400ah usable at 50% = lithium 500ah of which 400ah 80% usable. Just trying to to be fare with cost.
So am i, one more battery $75, and my bank would be 810amphrs for total price of $425
Surplus Telcom AGM batteries are available at a great price
Surplus lithium? Not near as cost feasible yet
New lithium, way to pricey
And while i don't go snow camping
We do run into cold mornings
And running heaters from the lithium battery pack to warm it up so you can charge them, is only going to lower the SOC some more making the generator run time longer,
Better make sure the solar controller is cold temp shut off,
So Not charging on that cold sunny winter morning
With lead batteries you can wake up on a cold morning and charge them,
With lithium, if you some how run them way down and wake up on a cold morning, you can't charge them, until you warm them up, how long does that take, how do you do it
If they are way down ? What is running the heaters to warm them up
run the heaters on generator for a few hours then begin charging the batteries ?
I'm not anti lithium, but you have to have eyes wide open, brain wide awake, when considering all the ramifications
