I am using a 4600 2s A123 (genuine A123) for my ECU that is supposed to handle something like 125 amps continuous and 250 amps burst. However, when I initiate the start-up, I am getting a low battery warning and no start. I watched the voltage on the HDT and it drops from 6.8 to about 6.6. Was anyone else having this same issue? If the pack can handle 125-250 amps, the 15 amp draw of the igniter shouldn't be a problem.

I have already been in touch with Eric and he is working with me on it, I am just curious what other people's experience has been for this particular combination.
