My ESC is only recognizing my 4s batteries. Won't even turn on with the others. Is this a programming/low voltage issue? How do I fix this?

It sounds like they are set to manual detect instead of auto. I had an issue on my old HW 150 pro, the big case one, with it auto detecting 4s. I had to go into programming and set it manually to only 4s. Software glitch I think. BUT when I would run a 3s, it immediately went into LVD because it was expecting to see 4s voltage.

One of the ESC's detected a 3s battery as a 4s. (4 beeps on startup)

Still seem like a software issue?

Yeah that's what I figure. Do you have the programming box? They make at least two for the HW esc's, if not 3 and they don't interchange.
