My Godox flash uses the PB-Cx power plug, same as Canon.

Im an electronics hobbyist and so no reason why I/we cannot build our own battery pack.

But I need some help, does anyone know what the pinout is for the plug?

Off the top of my head, Im thinking some 18650 batteries would make a bazinga power pack!

Once I see the pinout with voltages I can devise such a device.

Any success will be posted in this thread.

Thanks!
Andrew

The external power plug on these flash units requires approximately 300 volts that is supplied directly into the flash charging circuit.

Your best bet it to purchase a cheap external flash power pack and re-engineer it to use 18650 batteries instead of AA's.

Here is a diagram showing the pin connections on the flash external power plug.

Awesome buddy, many thanks for that data!

Holy smokes, 300 volts, from the link I am seeing what appears to be a buck circuit to boost the voltage way up..

Instead of re-inventing the wheel, converting an existing pack to use 18650s would indeed be the wisest option!!

Thanks again so much for the info!

Andrew
