The $150 coupon doesn't stack and falls off after using the code. You're simply getting 27% off of the $1000 original price.

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.

I am no expert of batteries, but I know many cheaper options use battery cores from unbranded factories or repurposed modules salvaged from damaged EV packs. I don't know this brand, but I know battery pack price varies 20 folds in China.

This is a good brand, new cells, not used or salvaged parts. This is less than half the cost of what I paid just a few years ago. Good deal.

so this battery can output 3.584 KWh. Wouldn't that be $100 per kwH?

I have 4 of the non Bluetooth version of this battery, I'm so tempted to grab 2 more to increase my storage to 21kWh.

I imagine the new tariffs are going to start effecting the price of these pretty soon?

No complaints at all. I just wanted to make sure that others aren't trying to get 150 off THEN 27% off

Last month tariffs were 145% lower than they are now and the US dollar was worth more.

This may be the last chance to get decent prices on a lot of things.
