Bad Battery Message / Battery Configuration Issue

Hi All,

I’m continually receiving a “Bad Battery” warning message on Mission Planner. Parameter files and most recent log attached.

Aircraft: Fimi Manta (Tri-motor VTOL)
FC: MatekF405-TE (and an unknown combined PDB/ESC board which came pre-installed with the Manta
FW: Plane V4.5.7

I’ve tried the following instructions in similar posts to no avail:

I get the same result whether I’ve set the battery capacity to 0mAh or to the battery capacity.

I’ve also tried switching to measuring voltage only. I’m confident that Voltage measuring is accurate

I’ve tried to calibrate current using the ratiometric method (Based on a previous log)

Finally, I’m aware there’s a whole load of other issues (pre-flight checks disabled, magnometer issues, etc.). It’s how it came from Fimi and I’m just trying to work through them.

Any suggestions gratefully received.
