Top shelf advice here :stuck_out_tongue_winking_eye:

I employed this very tactic with ahem varying degrees of success all through my 20’s :sunglasses:

Did you test the unwelded cell with a multimeter?

I’m curious if it actually is resting at a different voltage than all the other cells.

@Battery_Mooch it would be fancy if the electrolyte was able to be detected easily like applying a chemical test

I think it already has a feature for easy detection…its strong smell. Quite unique IMO.

Like rotten egss in natural gas lines?

I think he means that the smell is unique, not that the property of having a strong smell (and being a toxic material) is unique.

For me it’s definitely solvent-like but with a weird sickly sweetness too.

Yes I tested it and they were all at 4.03V including the unwelded cell.

Like mineral spirits with Splenda?

To me it’s pretty close to acetone, just a little more bitter-smelling

I don’t know what Splenda smells like. :person_shrugging:t2:

I hear it smells like cell juice

Speaking of nickel strips.

This is a kinda cool kit. I guess you could short the 13th cell on the BMS and run it with 12S. then maybe cut the cell holders and fit a dual vesc and crap all in that box.

I wouldn’t trust some generic unnamed Bms :man_shrugging:

So many ebike fires in NYC, it feels easy to blame a bad BMS for it.
