|The TRIO and the Quantum Turbo Battery|
I have been using turbo batteries for dozens of years to power my nikon flashes. It would/will allow your flash to stay charged much longer and for it to recycle much quicker. Which would help you not miss a shot waiting for your flash to recharge. We own four Trios one for each of us, one to put on a pole for additional light when needed and of course backup. If you are photographing anything and getting paid you need backups for all your lens, cameras, compact cards and flashes.
You cannot very well tell the person conducting the ceremony to wait while you go find another camera. I have had flash cards just crash during a wedding, not a happy day, thankfully there are companies that ( for a price) can recover your if not all most of your images. We typically shoot between 1000 - 2000 images at a wedding, you need cards, backup cards and more backups.

|Side view you can see the 50mm is quite small but a great lens.|
