Does anyone know the correct inside diameter for the DC coaxial connectors used on the Dinotte 600L battery? I measured it as 5.5mm O.D. but I'm having a little trouble measuring the I.D. My calipers measured 2.0mm, but when I compare a 2.0mm I.D. plug to the one on the light engine, it looks small, so I think my calipers may be a bit off. I have a few samples of 2.0, 2.1, and 2.5 I.D. plugs, and they all seem to fit on the battery connector, but I'd like to use the "right" one.
I'm building an adapter so I can charge the batteries on my Maha C777+, by the way. Are there any known problems with charging the Dinotte battery packs on third-party chargers?
