Re: Realistic expectations for my house batteries

I did say in that market.

My base point of comparison is $1-2 per Ah at 12V for lead, including transport to install location.

And usable capacity is not doubled, for good longevity compare 50% to 80%.

Please provide links to pricing, to build say a 400+Ah bank, for

Winston, CALB, GBS, A123 or Sinopoly, in large prismatic cells,

available from known-reputable domestic sellers.

Also adjustable BMS, if over $200 also use a domestic supplier.

I'm a huge fan of LFP, but there are many factors involved to get strictly economic ROI compared to lead, over a decade payback makes it very risky.

But lower weight, less space, no need to get to Full, super high CAR, no need for solar, the cool factor. . .

The reasons to "go for it" go beyond pure financial reasons.
