I had a lot of trouble trusting the battery monitor on Trixie. Even after calibration, it was frequently inaccurate, and I often had to physically remove and reinsert the batteries just to reset the counters. Even then, the readings were unpredictable. Since my workload is relatively heavy (mostly SDR usage), the system would sometimes simply power off around 30% battery remaining, likely due to a mix of temperature, current draw, voltage sag under load, and similar factors. Because of this, I…
