I say the heck with rechargables anymore. I just bought a Quantum QB1+ and the cord for my Flashes... Tired of changing the batteries all the time. This Battery pack will give me up to 1000 Flashes with no problem at full power. I know a guy that has the same Flash system as mine and the same camera and he gets over 1000 with no problem but that is only with the Flash. Not hooked up to the camera. The website says 250 with the camera and Flash but I am not using it on the camera...
Any thoughts??? Other than carrying it at a Wedding for 10 hours and it gets heavy... I already know that, I did that before with my film cameras...
