I am thinking of diving into the LiFePo deep end, with the above batteries.... unless there is less expensive option available?

 

Those are listed as EV cells and cost $0.312/Wh.

These are only $0.125/Wh and would be easier to deal with:https://www.alibaba.....5fc45e9fcebNbO

They are listed as 100Ah capacity and 3.2V, so 4 in series would give you 12.8V and 100Ah.

 

I know nothing about them other than what is listed. No idea if they will perform to spec. Or what they charge for shipping, although shipping from China tends to be pretty reasonable.

It looks like you could put together a 200 AH battery that would measure about 13"x10"x6.5".

I am corresponding with battery manufacturer now. The 100AH batteries are sold out. They do have 90AH battiers available. I have attached the spec sheet. Price per piece is $40USD and Door to door shiping to SoCal is $168USD. For a 180AH (8pcs) delivered would be a total of $468USD or $2.71/AH.

I will if I decide to go that route. I don't have or intend on adding solar. I only have alternator charging.

Solar is easy these days. You could get a folding panel that doesn't take up much space. They are handy too because you can park in the shade and set them out in the sun.

I know, but it just one more thing to deal with. I haven't needed solar in 11 years and don't plan on adding it now.
