Ardurover 4.2.2 on Cubepilot Orange. I have an Frsky Taranis radio and Frsky X8R Rx connected to RC IN w/ Sbus. When I power up the Taranis Tx, I get a “Bad Battery” error on the Mission Planner (V1.3.77) HUD. I can Arm, but when armed the HUD shows “Bad Battery” flashing quickly to “Safety” and back.
Messages do not give any indication what is wrong, what would be causing this? BTW, the Taranis Tx battery is fully charged and the 36V battery powering the rover is at 39V, connected to Power1. Battery Monitor is working and configured for low battery at 34V.
It was calibrated and measuring correctly. I found the power module (a cubepilot power brick mini) was only rated for 8S and I was using a 10S battery. I have changed to a 4S battery for now and still getting “Bad Battery” error so disabled the battery monitor. Will revisit when my Holybro 60V/12S module arrives.
I also learned about the “Safety” button, as this is my first time using a Pixhawk/Cubepilot, I did not realize what its’ function was, it is now disabled.
I now have the new Holybro PM02 V3 installed, supports 12S/51V. It is setup correctly according to Holybro’s guide, and accurately measuring my 10S/36V battery. However, I still get the “Bad Battery” error in HUD.
Makes no sense when the battery voltage shows a nice 36.6V in HUD.
Here are my BATT parameters:
How do I begin troubleshooting this??
Appears I was using the wrong pins for the Cube Orange.
I had followed * [Docs] » [Peripheral Hardware] » [Battery Monitors (aka Power Monitors/Modules)
and originally had:
No more “Bad Battery” errors, and both voltage and current appear to be measuring correctly.
