Start by reviewing commits 2c336fef6da34160c5334123ebde6bc97cb12b83 and 299c56d10f8c4a7bd2eabd2434f2f99f3cff440e, which added the Pixhawk 6C/Pix32 v6 hardware version. Reproduce the battery-monitor configuration issue in Mission Planner 1.3.79 by switching tabs, then compare the selected hardware version and BATT_VOLT_PIN/BATT_CURR_PIN values with the expected 10, 8, and 4. Done means the setting remains Pixhawk 6C/Pix32 v6 and the parameters update correctly.
