Does anyone know the name of or type of connector that is used for the output plug on Quantum batteries as in the Battery 2 and Battery 4? I'm speaking of the the power-out to the flash unit (photo attached). I want to use my Battery 5 (that uses an RCA style output) for duties that I use with my Battery 4's and need to wire an adapter. I went to measure dimensions just now and found my digital caliper not functioning so I can't measure easily and feel dead in the water and also couldn't find anything on the net.
