Calibration - no battery beeps

(Ivan Stoyanov) #1

Hi All,

I’m using APM 2.8 and I’m trying to calibrate the ESC “all-at-once”. During the calibration, I do not hear the two beeps for the 2s battery. You can see video here:


I’m still afraid to apply the throttle and check if the ESCs work. Do you think from the video that the calibration is successful? Is it possible that for some reason the battery is calibrated as 1s and because of that the ESCs burns?

Previously I had the problem described here: F450 ESC burns when throttle applied. I replaced the burned ESC for the third time. Also, I replaced the 4s battery with 2s.
