Missing Battery Parameter

PX4 Autopilot
1

Hello,

i am using PX4 Firmware Version: PX4 Pro 1.16.0 and am unable to locate the Parameter
bat1_v_load_drop. In the Parameter Reference to 1.15 it is still present Parameter Reference | PX4 Guide (v1.15) . I can’t find the parameter reference to 1.16 to verify it has been removed.

Does anyone know something about this?

Have a look at the changelog:

Battery level estimation improvements. (PX4-Autopilot#23205).

  • Voltage-based estimation with load compensation now uses a real-time estimate of the internal resistance of the battery to compensate voltage drops under load (with increased current), providing a better capacity estimate than with the raw measured voltage.

  • Thrust-based load compensation has been removed (along with the BATn_V_LOAD_DROP parameters, where n is the battery number).
