The Profoto B10 Plus Duo Kit is great to use for taking stills or video outside or inside when you’re running and gunning.  The kit comes with 4 batteries, each capable of generating 200 "full power" flashes - or - up to 75 minutes of continuous LED light (dimmable and bi-color).  With the Battery Charge 3A, the battery will recharge in less than 90 minutes.
