5V - not good should be 4.8<V>5.2
Fet's power voltage doubler doesn't work
Yes, and voltage should match output of doubler.

smoke not good, but what you can possibly short? All the power at fet's control is current limited...

Step one would be to fix 5V, than 10V. Go slowly, even remove/unsolder SO8 Fet's drivers (3 chips on the end) and restore power first. Check for shorts and blown components, remove power fet's board if it helps ( you do not need it for brains testing).

Defintely not for me!

I don't know what happened there, smoke came from one end of fet board, and from my battery terminals, everything got very hot quickly. Once it all cooled down I plugged in my battery again to investigate further and it started smoking and got hot again. I tried it again (lol) and this time nothing. No power to either board.

Actually I thought that you can fix it ...
