I believe that particular instance was a free public station.

I've taken it to 100 at a couple different public stations & my friends home Juicebox & my OEM cord.
 
97 cell voltages can be read on an iPhone with an ELM device. I am using Car scanner app and Kiwi 3. It needs a little trick: selecting 2nd-gen Fiat profile and pro version of this app (lifetime around $6). Diagnostic trouble codes function does not work properly because it cannot connect all the ECUs but you can get some stream data from BPCM.

It is 2 month later report.
Cell balancing is working pretty slowly, but it's getting better.
After the resurrection, I can drive with no anxiety in a 30 to 40-mile range per one charge.
Because SOC is below 30%, certain cells' voltage drops really quickly.
I think which cells are damaged. I wish to recover it.

So I got the lid off and behold... the beauty that is the pack

Full pack voltage was thankfully not zero. It was 30.0v. I'm using a DC power supply (60v max) to bulk charge. Putting it on the entire pack at 1amp... the pack jumped to 60v quickly. So that is promising. The weakest module is #18... the positive of the whole pack... furthest pack forward (6S). I read 0 volts... while all other modules read 1-2 volts.

So I'm on day 2 of charging. I've gotten all cells up to ~2.0 volts... with only module18 giving me fits... but it is taking a charge... just not as eagerly as the rest.

With a 60v max on my PS... I've divi'ed the pack into groups for charging. I'm in the process now of bringing the cells up to ~3.0 volts each. This will take a few days... but fingers crossed.

more to come. Cheers!
How do you test the cells on the 5s packs that are on their ends and the test holes are hidden?
