You’re right, upon further review you can get budget Lifepo4 batteries shipped to your door from Amazon for as low as $75/kwh, which includes cables, a BMS, and various Bluetooth connectivity. So $65/kwh seems fairly reasonable for raw battery capacity in very large quantities.

But now it’s time to better understand why a Powerwall or other wall-mounted units are so much more expensive. I understand UL-listing costs, marketing, warranty, and other things are thrown in, but it’s $75/kwh versus $1000/kwh, a 13x difference.

If even at a $100/kwh price point all homeowners need to get 10-20kwh in batteries just to help peak shave the grid and save tons of money since batteries will be a fraction of the cost of grid power.

Because Tesla wants their ~25-30% gross margin on Powerwalls.
