Video Conference Lighting Kit

I bought this because of the battery capability. What type of batteries does it use?

Whwhere do you get the batteries for thisere do you find the batteries?

Its says dosent include batterys so where can i buy the batterys so i can use it out side with out a cord ?

Does the carry bag have separate pocket or zippered compartment for the power cords, adapters, holder, remotes, etc?
