This looks like a great deal. 2 weeks ago I gave Aliexpress a shot and pulled the trigger on a DatouBoss 12V 100ah deep cycle. I never ordered from them before and it didn't go well. It was DOA. I got 0 volts out and tried to get it to take a charge in every way I possibly could. 2 different LFP chargers showed no power drawing from home AC. Now they're playing the merry-go-round of asking me for video evidence and pictures. I upload them and the same cycle starts again the next day. I'm on day 3 of this (doing all the uploads again) and if happens again I'll just go straight to file a CC dispute. I expected they would ultimately have me return it at my expense. I know we take our chances with any on-line retailer but Aliexpress seems a bit ridiculous.

I hope you figure out your return, but if you get screwed you could try bridging your new DOA battery to a charged one while the charger is hooked up, so the charger recognizes that it's hooked up to something. Then unhook the bridged battery and see if the charger does it's thing now.
It is concerning that your new battery seems to have discharged itself though. These lithium phosphate batteries are designed to be able to be drained to 0% and recharged, thousands of cycles.

I got in on that deal but mine never shipped and they just refunded my money. Guess I was lucky.

Thanks for the tip. I actually did that. As soon as I disconnected the bridged battery the charger shut off. I used a LiTime charger as well as a NOCO Gen 10. Voltmeter shows 0.0 volts. I feel like it's one of the posts internally not having contact. Maybe a cracked weld or something. Obviously don't want to void any 'warranty' by trying to get it opened. If it was just bad cells or BMS I should still get some voltage out and/or charging in.

Yeah that battery seems defective and internally open just like you said. Hope they let you exchange.
