Finally, I finished and posted a video about the BMS short-circuit current tester. This video just got the hell out of me - it was being made for almost six months, and four (fundamentally different) versions of the scheme were tried. The saddest thing is that the final results for the under-test BMS, which I had been going to use in my researches, turned out to be negative - the circuit did not provide shut down in the prescribed ranges of the output current duration and amplitude...
