Hi guys, I need your help... This afternoon I powered up my phantom, waited for the light sequence to begin, and right after the first set of green lights I'm getting a continuing rapid red light. Same as when the battery is low. I have 6 new batteries, all fully charged and this happens with all 6. When I connect to assistant, it gives me a low voltages error (VOL-LOW(4) even though battery reads 12.4V. Nothing I do fixes this. In fact I once even got a PMU-ERR message too.... The phantom flew perfectly yesterday. I can't figure it out. Any idea what might be wrong? Any help would be appreciated! My setup is: Phantom 1 with upgrade board, Zenmuse gimbal, fatshark 250mw Vtx. Using original phantom batteries.
