Recommended batteries for Canon Speedlite 600EX-RT - Camera Flash

What batteries should you use for your Canon Speedlite 600EX-RT? In this tutorial video I explain the two types of batteries that I recommend for use with a Canon Speedlite 600EX-RT. I am not paid by any battery company to recommend these batteries. They are simply what I recommend for “prosumer photography“ use with a Canon Speedlite 600EX-RT (camera flash). I hope you find this photography tutorial useful. - TheFamilyguy421
