Originally from July testing the prototypes.

The first production run sold out and should ship out next week to USA customers... Russia got theirs about a week ago so they are already having fun with them.

* DC Current Clamp

Derrick measured 7100-watts on MY Extech Clamp meter and captured 82v with his RMS volt-meter -- so we calculated that to be 0.95 ohms actual with rise from 0.33 nominal.

Voltage dropped to 12.3 volts with 646 amps of measured draw on my DC clamp meter.

We let everything cool off for a while and hit it again and saw 7200-watts as well but didn't grab all of the other information that round.

If we turned it up any more it would simply draw more current with no increase in measured power output on my meter.

We are quite happy with the performance as is Derrick :)
