Paul First of all , I misread the post. Just skimmed over it .. and I should have elaborated on my comment.
I know that most chargers will step up the voltage...actually convert to AC ,step up the voltage and then rectify it back to DC , but the ampreage also goes down unless your power supply meets the demand. It cannot rise to your needs unless you feed it.
I have a Triton , Astro Flight 109 D and regularly charge multi cell packs up to 18.5 volts. But , you can only get as much as the power supply allows. As the voltage goes up the current goes down without it. This is where I misread by skimmimg over the post. I was thinking no charger can step up the voltage and amps and thats what I should have posted.
Oh welll , it's good to get hollered at everyonce in a while. Just makes you more thankful for the quite times.
