I got myself a Mobula6 that came with 4x 1s lipos. While setting it up on the bench betaflight advertised around 3.6V. To make sure that bat calibration is ok I checked with a Capacity Checker. To my surprise that one read around 4.05V. I thought ok, calibration is off, I'll calibrate once I'm done setting up and doing a small hover test.
Well the quad did no stay in the air for more than 20s, props stopped spinning and that was it for the battery. I rechecked with the capacity checker afterwards and well the battery seems to be dead. The checker won't even turn on. I then went on to check the other batteries and they also read around 80% capacity, 4.05ish V.
Did they send me damaged batteries? Can I ress that dead battery or do something to prevent these other battery from dying too or to rescue them?

I've killed whoop batteries by leaving them plugged in too long while fucking with betaflight.
I use the whoopstor for my charger and also use it to check where my batteries are at charge wise.
Once they go below a certain voltage, I can't charge them anymore. If I'm flying, my vtx will brown out if I go too long. Discharging below 3v means lowered flight time/faster discharge on future flights.
Haven't had a battery refuse to charge after running it too low flying. I have had them refuse to charge after draining a battery on the bench or leaving it plugged in overnight. (cause I lost the drone and recovered it the next day)

I didn't have the battery plugged in for to long while configuring in betaflight. I only used it for flashing blue jay, checking if the vtx was ok and confirming motor direction. What really confused me is why the battery checker showed 4.0V which is like 80% charge and once I went into the air the battery died within 20sec
