I drained my original AD600Pro battery during a long wedding shoot, so it was great to have a spare battery for the reception dinner-dance. Glad I got a spare to swap in so I could keep shooting with a 60-inch Octa. It arrived the day after I ordered it online, well ahead of my shoot date.
Haven't had a lot of luck with Godox batteries for my Ad600 Pro strobes but after talking with the sales team, have full confidence that Strobe Pro will take care of me if any problems come up. Bought 2 and holding charge good so far.
