New Battleborn not charging

After a lot of back and forth with Battleborn without any help whatsoever, I finally cut it open and applied a load of 60w to the cells directly. That somehow reset the BMS and the battery is now working. You may want to try this if you have this problem. The BMS was also made in China, anyone knows the manufacturer of this BMS?
I have that same problem with 2 of my 5024 GB batteries, I want to cut them open and bypass the bms to recharge them can you let me know wher I should connect the charger negative cable?

There should be a wire (or a set of wires) connected to the input of the BMS (usually black) and there should be another connected to the output (usually blue).
Connect the negative to the black wire at the busbar. Attached picture is for reference.
