My idea is to use two Double D Holders with two AA adapters each from Camtraptions (this way each Double D holder will take six AA batteries), connect them in a row and then plug them with dummy batteries into the flash unit. This way, I will have 12 AA batteries and overall voltage of 6V (or 4.8V with NiMH rechargeable).

Usually, all battery holders of this kind use battery clip connectors for 9V batteries.

Unfortunately, the 9V connectors come with pre-soldered wires that are 26AWG (this gauge is not very thick). I can see that the wires in your pictures look similar gauge.

My question is: Is there any chance the 26AWG wires of the connectors can overheat during charging the flash unit?
The wire in the picture is 22ga and works fine for a short run.
