Godox 1 To 2 Y Adapter DB-01 For 2 X Speedlights

The DB-01 splitter cords are designed to enhance flash connectivity by allowing two flashes to be connected to each battery port. With this versatile accessory, photographers can efficiently maximize the usage of their equipment, ensuring optimal lighting setups for their photography projects.

So up to 4 flashes connected to each battery pack. (When 2 of these cables are purchased.)

Using these cables will have some effect on recycle time, but the PB960 could easily handle 4 speedlights. It is quite similar in capacity and speed to using four separate 8 AA cell packs.
