I bought a Konica Cube Flash adapter, since I have a bunch of unused cube flashes, so that I could use them on any camera with a hotshoe or cable connector
The thing is: it uses a 15V battery and it's crazy expensive and hard to find where I live
I was planning on adapting two 9V batteries connected together to charge it
Does anyone know if it would work fine? It's 18V total (not too much above 15) and it's basically just for firing the flash, so I believe it would be okay, but would like to hear from people here
