One thing I noticed Marty when I was playing with the A123 batteries was that the voltage on the packs went down as low as 6.3 volts when commanded to WOT. The cutoff is 6.0v for the ECU. It was a bit close for comfort for me. I'm thinking that with a battery thats not up to par, the voltage would drop below the cutoff and thats where problems arise. I'm no expert but I thought that these batteries gave a continous 6.6 so I was surprised to see the drop.
