I have recently got more sealed lead acid batteries so I can now power my ZVS flyback driver up to 36 volts! I will try find some time to make an instructable about making one of those beast, at the moment, I can show the vid of it working....

Here is a video of the coil running in audio modulation mode at 90 volts (this was an earlier test, so the arcs became longer later on) F...
