Stock Batts: it can be done
 

I just got through an entire days shooting with only three of the crappy stock batteries and it was on a fair amount of the time. I switched it off after every take and never used the lcd and i think i might still have a little bit of juice in the last one.

It was a good day up untill i got flashed by one of those damn cameras when i jumped a red light by a fraction.......that will be three points on my license then Ba###RD!
