Semi-integrated Battery not Working with Black Wrap not the Blue

[Stive22]

The bike is a Rad 6+.

The semi-integrated battery does not charge. The charging light is green. There are no lights on the battery. I have tried the shipping mode release. The charger works on my other battery. The internal battery has the black plastic wrap. This one does not have the same fuse as the blue wrapped battery. When plugging the charger in, I get 48v on the end of the battery (outside connection). It diminishes quickly when I unplug the charger. I have left it on the charger for several hours with no change. I have not tested each cell yet. I used my DMM for continuity on the soldered in tiny little fuses with no issues. I noticed there is a "RST" hole in the BMS. like other known batteries I tried touching the "RST" with the "GRD" and it did not reset.

Has anyone had success in reviving or fixing this black wrapped battery that does not seem to charge?
Thanks
