Dell Laptop lipo re-use

Hi!
I got 200 of these lipo packages. It is four cells, 2s 2-paralell. 51w
Probably there is some kind obattrey protection/balancing circuit inside.
I would like to find a matching connector for this battery(see pic). The pitch is 1.8mm. So far i havent found anything similar.

The most lookalike i have found are these molex pico-lock:

But the pitch is wrong.

Additionally, the BMS inside some laptop packs will not allow charge or discharge without communication with the laptop itself, thru that connector.

Or, it might allow it, but be unable to actually protect the batteries if there is no cutoff FET in there, because it could depend on that communication with the laptop to tell it to stop charging or discharging, rather than actively doing that itself at teh pack level.

You'll have to test that before continuing, if any of that matters to your project.
