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

If I may ask: how accurate is the max.Ampere rate
coming from the Hobbywing ?

My 130V4 shows 180 Ampere as a maximum in a 700 Rex
when the Unisens-E says 130 Amps, and I trust the Unisens
"a lot"

I use IISI to compare and during normal flight I got quite same results on peak current.
If I really go hard on sticks I do see higher currents on Telemetry HW (189A) than IISI (154A). Well this is peak and hard to judge I could only tell if compared with high quality lab equipment. IISI might do some filtering or does integration to build average. Do I care? Not really, for me only used Capacity as well as min Bat Voltage is relevant Peak I is kind of nice to know.

Beside I got asked on my HW Setup:

HW in Gov Store Mode
Had to reduce P and I Gain to get solid tail as values where a bit to aggressive.
Bailout working perfect with this setup as well.
I use rpm cable, but manual sais rpm should work with ESC telemetry only as well.
It requires Gov Setting in Spirit like Gear and Magnets/2 to get right numbers (Select / enter / de-Select Gov tick)
