I am picking up another Pro B2 so another 7B has to go for sale! These are selling for 4200 on BH right now. I will sell mine for 2000 NET. Shipping should only be like 40 or 50 insured, and cheaper if you don't want insurance.
The battery holds about 90 percent from full charge. I have never had the battery die on me during a shoot. As you can see from the pictures (sorry about the quality, I didn't want to setup the studio) the pack is in excellent condition. Comes with genuine profoto charger.
Price: 2000 net
