  Hoppy:
  Thanks for the tips.
   I have a question... My two small 12v zener diodes that are on the Mazilli circuit are conducting both ways. Does that indicate that they are burnt out? They conduct both ways while they are in the circuit, I have not tested them out of the circuit. Maybe the cause of overheating of the Fets?  As these fets should be able to handle the voltage/current levels from a 12v 4aH battery.

  Concerning Ruslan. Something always happens to interferes with getting the proper circuit information when a self runner is shown. Never fails. Does not surprise me, but I still hope that he will come through with the goods.

  Acca:  Thanks for keeping in touch with Ruslan.

The Zeners are meant to protect the gate from over voltage; if you haven't blown up any mosfets it probably won't help; it won't help them be any cooler... they should be properly 'slammed' to conduction when there's no voltage across the source/drain (or basically none) so it's shouldn't be an issue of just partial turn-on; you're just pushing that much power through them.... only solution is to put more fets in parallel....

   If the zeners  are burnt, they won't be doing their job of protecting from overvoltage or current.
Other guys have run this same circuit up to forty volts without overheating the fets, when using the 18v, 5 w zeners. I just can't obtain them here, yet.

My power supply only goes up to 30 volts; but mine ran cool... but then I had low gauge wires which limited the current
right; if they're burnt the circuit won't function because the gates will never go above ground... so I thought you were running without them at all; when you added them they got burnt but then your system would be stopped...


what's the millohm on rating of your mostfet vs theirs?  if your is 5mO and their is only 3.5mO for instance there will be a lot more heat of yours.... the zeners really have nothing to do with heat, they're only to save the gate from over-voltage and popping; which will make the mosfet be open in all directions
