Electronic SOURCE is RC 3S 2200 mAh LIPO BATTERY (45C, capable of delivering 99 A for 1.3 minutes so if Constant Current Electronic Load is not regulating , it can get real ugly, real fast !)
I tried to read the rest of your post, but every 30 seconds I just kept going back up to this. That's just gnarly.
And forget the 20 year old multimeter, that oscilloscope is probably older than my dad.1 What's the V/dic and s/div settings, the picture angle doesn't let me read them off the knobs. That looks like some terrible oscillation on the output there, but I can't tell without knowing the scale.
- Looked it up, and apparently it's only about 6 years older than me. Way off the mark.
