I got in on the 1st deal, back in October, where it was $720 with the eBay coupon. There is a 67 page (currently) on the DIY Solar forum https://diysolarforum.com/threads...ery.92299/ . The initial version of this battery has issues with the BMS settings, among other things, CAN communication cable was missing. If you use the right software tools settings can be adjusted.

There is an Eco-Worthy representative that is active on the thread. EW listened to the comments of forum members and made improvements in the version listed here. They have also made good - at least to me and several others that had issues on 1st gen of the battery, with a new BMS to change out with the one in the original, if you are capable of making the change. I would note that the terminals are reversed orientation of most other server rack batteries.
"10-Year Warranty: Featuring rigorously tested, high-consistency A-grade cells for extended lifespan."

is this something we can just believe at face value? or should we look for a teardown video

Will Prowse has a video out...

And it's not that great, the cells are a bit meh, tests came out at 96% on one unit, the others barely were over 100, and one was 105... (105 would be what you expect on a new unit).

He posted an update just recently and apparently the new EG4 battery is even worse.

Prices on these seem to keep going up instead of going down. I guess with new tariffs I need a time machine to get these at $700.

These guys are suspect. They don't give good tech support and their batteries are prone to under-current issues.
