Things that make you go "Hmmmm?" about batteries. Tesla Motors (TSLA) is set to announce a new product today...but it's not a car. Speculation is CEO Elon Musk will unveil batteries for homes and ...

I think those high voltages would be more of a p.i.t.a. than what it's worth... unless one went with 120v only, in their rv.
But at $3500 for 10kwh, that's about 3x the cost of flooded batteries:
10,000Wh x 70% (usable power) = 7000Wh / 12v = 583Ah x 2 (to allow for 50% dod) = 1166Ah flooded bank, at say $1/Ah for a 10x 6v series/parallel bank, = $1166.00
$3500 / $1166 = 3
I've found most LiFePo4 to be about 4x the cost of flooded.
