From a technical standpoint:
vaping is a burst/pulse function. Pulse ratings are fine to vape with, as long as you know what you're doing, and you don't discharge at those current levels for longer than 60seconds- which is what a burst usually is rated at(above continuous(20-lg or 3-0vtc&25r))
And specifically:
Mechanical- the vtc3-5 have 30Amp continuous, and the burst rating is supposedly 60 Amps, but I've read about people pushing over 100 Amps. I don't know if that's true or not..the vtc5s get much warmer than all the others, so I stay around the continuous rating.
Ah.
Someone posted on ECF a scanned tech spec sheet of the vtc5. Most of it was Japanese, but there was a table for the various amp discharge.
For different pulse duration, the discharge rate sky rockets. Gonna see if I can find that for you guys.
ETA: here you go
