I have bought a B80 expansion battery to augment a EB3A. I have the aviation plug to dc7909 cable but want a socket for the aviation plug. The plug is made by Jnicon, but the description on their website is confusing, although my plug matches one of the pics. The B80 has an M23 2-pin with 2 banks of 4 pins, I think the convention is to describe it as an M23 2+4+4. However the description on the website and one of the photos describes an M23 2+1+5. The Jnicon sales people make no sense and they sell only multiples of 1000 units. I want one. Has anybody found such a socket elsewhere or resorted to rewiring using a vanilla 2-pin aviation plug? Keen for your input or ideas, thanks!
