I do think we'll see sub-500-ish again, and I think there's a reasonable chance of seeing $450–$475 during one of these major AliExpress promotion.
AliExpress has several recurring sale windows, but there are really 3 I watch
Roughly Aug. 28–Sept. 5 — Back-to-School / Choice Day promotions. This is the next window, so I would definitely see what happens to that $514 two-pack before buying.
Roughly Sept. 9–13. This is another meaningful sitewide coupon period and could easily knock another $30–$70 off a $500 battery order if ECO-WORTHY participates and AliExpress stacks a site coupon.
November 11, usually running for several days. This is the big one — AliExpress's largest sale of the year. In 2025, AliExpress officially ran it Nov. 11–19 with discounts up to 90% plus payment promotions.
Then Black Friday follows immediately afterward, generally late November into early December, and 12.12 is another decent sale in December.
SOOOO I would not buy the $514 pair today unless you need them immediately. I'd watch Aug. 28 through Sept. 13.

Only issue is they will only allow you to buy 2.
4 x 3584wh = 14,336 wh = $1010
EW 48V 100AH INFO: Price $580 each for now, 5120wh, weight 44kg (97 lbs). People buy this for easy storage with EW RACK and look appearance. The price is much more expensive. If you have money and go for it.
3 x 5120wh = 15,360 wh = $1740
Both of these batteries are using BLUETOOTH APP to check battery status. If you get 4 of 12V 280ah, you could buy a "Metal Utility Wheel Cart". I bought one few weeks ago for $28 on Walmart to put 4 of 12V 280ah on it. I show you the bluetooth app of my phone for battery status of 12V 280ah and the metal wheel cart below.
