I was having too much voltage fluctuation in my telemetry reading causing my Taranis to keep warning when reaching close to the criteria value and I found that connecting the vbat to the lc filter would solve this issue and make the voltage reading more stable but notice that lc filter will cause some voltage drop so the value must be adjusted in Cleanflight "voltage scale" to match the actual battery voltage.

liked to share the info.

Cool idea indeed!
But if your voltage drops too much during punchout probably means the C rating isn't high enough?

What packs are you using?

I'm using all 3s for now different mah, models and C rating
The ones with higher C are better in voltage drop thing but in general the fluctuation was there.
