How does he estimate DIY 15kwh @ $3k???

[AROJANDRO]

Can anyone help understand what he has in the Tupperware bin, that gets him 15kwh in that size for that cost?÷/
Most helpful, as I've been trying to rap my head around the cost of building a kit or two for recharging tesla off grid.
Looking forward, Thnx=]

16 x Eve 304ah cells at 48v.

Say $2500 for the cells, $200 for the bms, $100 for fuse and switch, $200 for the rest?

Give it take?
