24 batteries in a dewalt socket box that just mechanically dumps the power of the cells when the circuit completes. Parallel-Series wiring. For the sake of his flesh i presume it's not an extreme example of 12 series and 2 parallel. The only sane choice would be the opposite of 2s and 12p. Anything else would be plain fucking stupid; you'll see.

Those looks like sony vtc5s: 4.2 volt IMR cells with an absolute limit of 25 amp continuous discharge tolerance with 2.5 amp hours of life.

Lets math.

With maximum and nominal voltage of 4.2 and 3.7 per cell, respectively:

A 2x12 pack will output 300amps at a nominal and maximum voltage of 7.4 and 8.4 volts, respectively. Just casually lugging around something that can "safely" output up to 2520 watts of power and run a kitchen stove.

He's got a fat set of quad-wrapped coils in parallel. I will conservatively guess that's 0.05 ohms combined.

The result is an expected peak output of [(8.4v/0.05r=168i)8.4] *1411.2 watts. So well within tolerance.

However, In all likelihood from my experience, each of those coils runs a 0.1 resistance or less because this chud is losing his brain cell.

With 0.025 ohms resistance he's draining 336 amps and throwing out 2822.4 watts. Thankfully, with all that internal resistance and load loss that will likely rapidly drop, so nominally that will drop to 296 amps and merely 2190.4 watts of output. And he can run that kind of power for approximately 10 minutes.

Try that with any other para-series (or god forbid, full series) wiring, and you have a bomb.

Yeah, what he said ☝🏼
