I’ve got one of these in my build! Mind you not the exact same model but it’s this antbms

Haven’t had any massive issues with it yet performs fine lots of settings to mess around with.
The 2 issues I have come across are a little annoying tho. First off one temp sensor was broken displaying - 30 which didn’t allow the battery to charge (there’s overrides to disable the temp protection and I’m sure it’s a 5 cent replacement sensor but sucks either way).
But the bigger issue is I can’t get the precharge ciruict to properly work, no issues turning off the discharge mosfet’s but when trying to turn it on again the Vesc begin to flash but never properly boot up and the bms gives an error saying the precharge failed. Theres a precharge current adjustment in the settings but no luck fucking around with that.
So basically you can’t turn it off and on via Bluetooth without a loopkey which is annoying for myself as I prefer to run charge port only boards
But it by far has the widest range of settings in the app and a 200mAh balance current which is nice.
As far as BMS and cut outs go I’ve never had any overspecced discharge BMS’s I’d say 99% of issues with bms are because they aren’t designed for our applications and the factory settings are to conservative or incorrect.
When you’re able to adjust pretty much all the bms settings to whatever your liking you can gear your battery to be as agressive as you like.
Edit: added some app pictures. There seems to be a cleaner English translated app that came out recently haven’t been able to find it yet however.
App is called MaYi bms
