Hello
In the early stages of tuning a large HEXA X multi-copter using T-motor P80-100KV motors, Alpha 80A ESC and T-motor MF 3218 props.
When doing hover tests the system is experiencing battery failsafe because of voltage sag (attached is a log from a hover test). The batteries used in this log are two Tattu 6S 32 amp 10C connected in series by the power distribution board. Because this is a new build, I’m somewhat paranoid regarding setup / design.
I’m using two Mauch PL-250 sensor boards connected to a Mauch Sensor hub which is then connected to a Mauch power cube. In MP the Voltage Divider is 19 volts and the Amps/Volt = 153 (which is the sum of A/V data from Mauch for two sensor boards). With no load the voltage I’m seeing in MP correct (when comparing to a battery tester / multimeter).
Of course, I can set the critical voltage failsafe lower but wanted to confirm if this level of voltage sag is ‘normal’? I’m guessing the battery monitoring set-up is correct and working properly, but maybe an issue there?
Thanks for any thoughts and comments
