How many PWM?

[Mindcrime13]

hello, im planning my set up using 2 HHO cells, would i need 2 PWM or one?

thanks!

IMO you would need two, one for each cell. The reason for this is no two cell are alike and each one will have it's own resonate frequency.

Depends. Are you going to finely tune the PWM's each time you start your car? If not, then it doesn't matter, because you won't be anyplace close to the frequency required for super high production anyways.

so how the connection would be from 1 PWM to 2 cells?

What's the current limit of your PWM? Make sure your cell's don't draw more current together then it's limit. Just wire them in parallel.

so if the pwm is a 30 amp, each cell cannot draw more than 15?
