Hi Darrell,
I will send you a free 40 amp Constant Current PWM with digital amp gauge



If you will post your results here on the HHO forums

You will need to run your cell at less than 40 amps RMS

Peak load (cell ) can be 50-60 amps

If sombody else thinks they need a PWM more tha Darrell feel free to beg.
