Hi,
I have a new Tattu 22000 mah (or bought from a guy who had it unused all in package and clean and so on), don't know how long had been sitting. But however, I get flighttime around 10 min and after that I have like 21.2V left and I come down. When I go home and charge battery to "storage" I see that it discharges a little and then it's done. Doesn't this mean that there's around 50% or a bit more battery left (since storage is in 50%?). And as I understod you can use 80% of the battery? So why it drops so quickly to 21.2V? Or can I just change the lower limit lower? Or are the batteries so bad even though after flight there's so much left? Or is there just something I don't understand about these batteries? Same thing with few batteries that came with copter (these were used ones)
Checked and app shows the voltage pretty much correctly (like +/- 0.1V).
Regards,
Madis
