Folks are replacing thier Battle Borns with these higher capacity (and far cheaper) alternatives...and this particular unit is about half the cost of other similar brands, when those brands have their own issues.
edit: BTW, these may have the 'new' low temperature cells inside:
Discharging Temperature
-4~167℉/-20~75℃
Charging Temperature
19.4~149℉/-7~65℃

Edit: This appears to be a clearance model, in favor of the V2 model (V2 upgraded 314AH cells, shows an angular image on the monitor screen). Oddly, the eBay listing specs don't jibe with their site's specs, so need to ask eBay directly if they are low-temp cells.

Hard to choose between this one and the other eco worthy 280ah (but often reviewed closer to 300ah) for 239.79 on aliexpress.. This one has a battery indicator and nicer looking case. Don't know of much else difference, but the built in battery level lights are defenitely nice to have in case BT isn't working or something.

Ive been following the Battle Born debacle on Will Prowse's youtube channel. Im so glad he took the leadership role in exposed their dangerous monumental failures. Hard to believe such a respected company destroyed their reputation to save $2 on their VERY expensive batteries. I own several that died similar deaths and will be joining the class action suit to see if I can recoup my money.
As far as asking if this listing is V2 on ebay, I wouldn't trust any answer they give me. Its a roll of the dice, assuming paypal will protect you if you get V1 and if eco worthy will pay return shipping.

I'm sure the listing is V1, I was thinking about contact seller for low-temp cells question, but after thinking further these are NOT the new low-temp cells. I don't think V2 has them yet either. Seems the sister company DC House has a low-temp unit with the cells, and wondered when Eco-Worthy will get them too, beyond the Cubix Pro.
edit: Good luck with your claim, hope for some restitution!
