I was replacing AA batteries in my speedlite at the same time I was replacing LP-E6 battery pack in my 7D. And for the X time, I was wondering if it would be technically possible to make new speedlite flashes to use Canon battery packs. Physically, I think it would fit in size.
For power, 7.2v 1800mAh pack versus 6x1.2v 2500mhA rechargeable AA's, would that be enough? Replacing one single pack instead of 2x AA's heads up and 2x AA's heads down is much, much faster. I was recently using a Marshall monitor and it was also sing LP-E6 battery packs. So I thought that it would be convenient to use the same battery pack in everything.
What do you think? Would it be technically possible? Would it be relevent for you?
