FWIU they are very noisy RF wise . also see if you can find out the duty cycle of the charger . i doubt it's %100 at the amps you'll need for a 12 pill if you run it at %200 - %300 of the pills rated power they way most CB'ers will run them ....... not that 255 amps is enough for 3600 watts .

but try it and let us know your results .
