Quote from wildbird12 :
Wow - $365/battery under $0.1/kWh

Edit: oops - as others pointed out, I calculated cost per Wh, so x1000 per kWh makes this around $100/kWhWink . The point is that this is a terrific deal for a quality battery of this size.
8 batteries is about 25kWH, and price on amazon after coupon and tax is $3000-3200 depending on tax rate (5-10%).

To be more precise: 4x$730 [=$2920]/8x3.564kWh [=28.67kWh] = $101.85/kWh (btw no tax in Oregon and other states but possibly 30% tax credit)...

Compared to? This is almost as cheap as building your own. This likely has Rept or Hithium 280AH, a 200A BMS, 2GA wire to terminals.

Nice I paid ~$800 for the pair a year ago on previous eBay sale without Bluetooth. Running my off-grid 3000W hybrid inverter. 7.2 Kilowatt hours is plenty to blast a window A/C 24/7. Good deal

Your math breaks down when you price a nice waterproof enclosure with screw terminals! Not worth it unless you need something custom you can't buy.

Precisely...when these go on sale with a stackable discount, it's hard to beat even DIY. As cell supply dries up, I can see some even scavenging from these new complete units to fashion a particular custom config.

What are the main differences between this and the server rack version that generates 5kW whereas this one can generate 7kW for roughly the same amount of money?
