So that’s all it was. Some bad connection somewhere. I just swapped the BMSs and it turns out they were both good. So glad because I was planning a Alibaba order of a bunch more JBD BMSs.

Now to find the dodgy connection :grin:

so. I accidentally sliced a lipo cell with a razor knife. how to dispose of it?

it had no tab left exposed, but I wanted to discharge it for recycling. so I was cutting away some of the wrapper to expose some tab.

just when i was almost done, I slipped and sliced a tiny slice in the pouch. got my first sweet smell of success. (electrolyte)

I decided to FAF, and i setup a firesafe area, and went ahead and discharge/destroy the cell. it didn’t catch on fire. and it’s dead dead now. smells sweet still tho.

what can i do with it now? can I take it to the recycler? maybe I could super glue the hole… tape it… and… then take it to the recycler?

I wouldn’t recommend superglue. You never know what kind of chemical reactions could occur between the glue and the electrolyte. Personally, i would tape it up, double bag it, and recycle it. If you fully discharged it then there should be zero potential to start a fire. So the bags are just to keep the highly toxic cell guts from getting out.
