Hi Javier

I've calibrated the battery monitor as per your link and it is reading correctly, however it is the constant low battery warning that is the issue. It is sounding when it shouldn't.

The firmware is compiled using the PX4 Toolchain, from the source code in Please check the following guide for more information:

@Phil Horner

Maybe your battery monitor is not well calibrated. Please check In particular, you can input the voltage you're reading (23 V).

Hi all

I'm having a problem with the low battery warning function on my Pixhawk. On the HUD screen in Mission Planner, at the bottom where it shows the battery voltage and amps, it is always in red and issuing warnings that the battery is low ie, 21volts. Yet the Voltage is actually reading correctly at 23 volts. Can someone please point me to a link that demonstrates what I can do to fix this issue? I must have altered a parameter at some stage, because it used to work flawlessly.
