ah screw it -
I was just asking for a clarification.....

I have studied electronics and I don't understand how you can squeeze more amps out of a closed circuit with resistance held constant and you actually have less voltage to work with. Its kinda saying that you going to keep the hose the same size, turn the water flow down and somehow the water pressure is going to go up.

I'm just figuring I'm missing something.....[&o]
I was looking at watt requirement - lower the voltage -you have to increase the amperage to get same watts
but not ignitions are done the same way - what may be a problem tho is that LiPos as they run down drop to under 3 v as the primary stage of the ignition is "loaded " the A123 holds voltage under load right ondown to about 80% of charge

also the IC(if they have one) may have a threshold which is close to 3 v
anyway run what you like-- if it quits - you will know the test did not work.
