Please help with this project, it will be rolled out to the community.

I am working on building a power pack DIY style for my Godox flashes, which use the Canon Cx type socket.

I am unable to locate the plug or the socket by it's self, so I will be needing a junk bin Canon flash that takes
and external power pack to reverse engineer the connection and determine the voltages and polarity of the
socket.

I am also in need of a power cord so I can get the plug off of it.

My end goal is to be able use use the common 8 pin DIN plug power cable for an 18650 battery powered
external power pack for Canon (and other) flashes. These batteries, if you did not know, are inexpensive,
hold a shelf charge for a LONG time, recharge pretty quick and have lots of m-amps to deliver, making the
AA battery look like a Ford Pinto beside an old military 5 ton truck!

I could possibly chip in a few bux over shipping charges if you can help with the project please.

The flash does NOT need to be functional, I will be taking it apart to examine the wireing of the socket
and to cannibalize it for parts.

Why not just Amazon it?

Not sure why, but call me JJ.

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.

Ive dug that up a dozen times, I was searching for just the PLUG, should cost $.60 on ebay with $1.50 shipping, wasnt trying to spend $13 on something I was going to put the wire cutters to..

However, that may end up being my only choice if I am determined to get a plug..

Thx,
Andrew

I saw your post on my circuit request thread, thanks much.

Since I will not be building a buck to deliver 300vdc to the flash, Id rather simply modify an existing battery pack for my intended use.

Previously I had no idea of the circuit involved, I presumed that the battery power was directly connected to the flash.
Now that I see that is incorrect, I can appreciate WHY they cost "so much", the cheapest I found was $25 on Zon.

Thanks much..


Please consider this thread closed.

Thanks all,
Andrew
