Certainly good questions. The Powerpak III seems to be just about like the Powerpak II which can also be used on the AF400T. It would be interesting to find out what is different between the II and III version. I have several weddings coming up that it could be used with, but I need the fast recycling time of the battery 2 - the powerpack's don't seem to have near the recycle speed.
Let me know if you decide to experiment and what you discover. -- Bruce Wednesday, February 21, 2007, 8:48:15 AM, you wrote: pcn> I asked Quantum if I could use the battery 2 power supply pcn> with the AF-540 FGZ.
