Failsafe issue

Posted by walthero on December 30, 2012 at 6:22pm

I'm used to fly KK2.0 with low voltage alarm (buzzer). Is this possible to set up in my APM2.5?

    You could just purchase a external battery monitor and buzzer. It would plug into the LiPo's balance cable. That's what I use. Below is a link to what I'm talking about.

    I know i can do it this way, but i would like to have an option (from the board it self) when i fly without MP. Connect a buzzer to a port some way.

    Yes, with the APM 2.5+ Power Module, you can measure both low voltage (not so useful, due to sagging) and total battery capacity left (much more useful). Both of those are displayed in the Mission Planner if you have telemetry enabled. 

    If you want to write a script to sound an alarm when those levels hit a certain point, you can do it with the built-in Python scripting.
