Gobel battery experience?

Anybody have experience with Gobel lithium 12 volt batteries? I was hoping to find a Will Prowse video of him tearing one apart and a recommendation, but if one exists, I haven't found it. Are they good quality?

I Did buy some of these battery's as the pricing was very competitive. Quality is good the JBD BMS with bluetooth seems to work ok.
There are QR codes on the battery to download the BMS app and to add the battery to the android app. Works fine.
Also the casing seems to be watertight. One downside is the internal cells seem to move a little when you shake the case.
Performance was on par, i think the internal cells are Hitium 280Ah. The carry strap is al little flimsy. Great buy, so far!
