Just want to thank Tomas for this great new implementation.
Give it a try. I'm running HW V4 120A on my Soxox 550 with new FW 2.4.1 with Horus FrSky transmitter.
After first fly and recharge, I adjusted I shunt to 95% and now it matches up on charged value.
I'm using alerts on BEC- and Battery-Voltage as well as on consumed mAh reported from HW ESC to Spirit and back into my TX.
Flying with low rpm for 8 Min and 3D for 3.5 Min and it matches. No additional Sensors just one cable from ESC to Spirit Sat POrt and your done.
No more guessing based on timers, fly on gauge.
Well done, big thanks
