Hey Michael, according to the manual of my new acquired 550EX, you indeed have to be sure there are 4xAA of rechargeable inside even if you use turbo pack for main power source for the flash. The internal electronics circuitry is powered by the batteries, why the tube energy is supplied by the external pack. ---------------------------------------------------------------------------- -------------------- OK, time for reality. I use a Quantum Turbo with my 550EX flashes. Quantum provides a dummy cell that you substitute for one of the 1.5v alkalines. This minimizes the drain from the AAs and the 550EX relies on the Turbo battery for nearly all power. Now I cannot speak for the Canon power pack, but if it uses the HV input it should be the same.
