Hey folks, so here's the scenario. I went out and flew 2 batteries on a 5" quad that I built. I've flown it a number of times with no issues and this night was no exception. Two great flights. Landed softly. When I put the 3 battery on, the ESC makes the first 3 tones, but doesn't make the last two and the quad won't arm. When I hook up to betaflight and put a battery on, the little battery indicator at the top of the screen with sometimes flicker. When it's solid, it's only reading like 4.2 V (like a 1s battery even though it's a 4S), so it seems like a low power condition. This happens when I connect ANY of my 4S batteries to that quad. Then batteries check out fine and on the battery checker and when I hook these batteries up to my other quad when it is connected to betaflight, it shows 16.2 V. So, I'm comfortable that the problem is with this quad and not with the batteries. When a battery is plugged in and I jiggle the XT60, it does not seem to have any effect and there is no visible damage to the XT60 on the quad or to the wires. The power wires are firmly soldered and I am using a capacitor soldered on with the power wires. Stack is the LDARC 30.5 x 30 5 mm KK Superfly Tower with a 4-in-1 ESC. Also, the quad will not link to my transmitter. However, I THINK this is because the frsky receiver is not receiving power.
I was thinking of just flashing the firmware in case it's just a gremlin, but it really seems like the quad isn't seeing the right amount of power coming in.
I'd be interested in any troubleshooting ideas or thoughts on what might be going on. Please let me know what additional info you need for a diagnosis. Thanks in advance.
