YONGNUO YN568EX Battery Adapter

thingiverse

This adapter can be used to modify a YONGNUO YN568EX for permanent installation without batteries. Simply connect a 6-volt power supply and you can use your flash all day without battery changes. For completion, you will need: two M3 screws, some wires, a soldering iron, and a 6V power supply (5A would work well for about 3-4 seconds of recharge time). Solder the black and red wires to the side of the head of the M3 screws. Then install the screws into the adapter, allowing them to stick out about 2mm. The black/negative wire should be installed on the lower (flash-shoe) side of the adapter. Depending on the thickness of your wires, you might want to grind a small notch into the battery cover of the flash to allow smooth wire feedthrough. Have fun!
