I'm not in the war but I followed the entire episode.
Sorry, it's nearing the end of my work day and my brain is fried - could not compute your explanation for now.
The thing is I only have 2 batteries for my V939. I am using the non-balancing parallel charging harness, 2 batteries parallel connected to a JST each, then the other end to the charger. Set it to charge at 0.8A (0.4A each), 1S 3.7V. But before
that, I would need to allow the batteries to self-balance, equalise for 10 minutes.
With this new found device, I would charge it at XA, 2S, 3.7V. There is no need to allow the batteries to equalise.
So back my question: This thing has 3 ports. I have 2 batteries. Will it charge? Or will the charger report battery error?
