Anywho, Asutin took good care of me. He's letting me send it back. So that's good. You ahve been awesome Brian. Austin also asked about my wires being too long going to the batteries as well. They are about 4in in length if that, so i don't see that being a problem. But funny that you said...
"but the charger apparently computes the max charge current based on the voltage, so the current steadily falls. At any point in the charge, you can multiple the voltage by the current and it will be exactly 120w. Kinda like a cross between a constant current and constant voltage source - a constant power source!"
Because once the volts are up there, my amps begin to drop

Cool, I'm glad he's easy to deal with.
About the amperage dropping thing: the charger will do that anyway when charging lipos (no matter what current you are charging at) and the pack reaches 4.2v per cell - that's the constant voltage stage.
