Does any one have any experience/tips/suggestions for battery systems? and specific models?
I'm shooting a lot of bicycle racing among many other things, with my 30D and 580EX
I've heard of some problems with Quantums and Lumedynes, and I don't know a lot about anythingn else.
So what do you use? what model? In the end, what should I go buy now?
thanks! -Peter
