Will Flying Down to 0% Level Damage Battery...?

[allen_993]

Is there any damage done to the battery (or solo) by flying down to 0% battery level? I flew down to 0%, just see what would happen...like I really need to see if it can fly with no power. . I did it in the grass at about 12" altitude. It didn't fall when 0% was reached, so I landed it.

Anyway, now that particular battery seems to operate normally from 100% down to about 25%, then drops much more rapidly down to 15%, 10%, 5%, then 0%. I read somewhere that it's not a good idea to go to 0%, and I'm wondering if I've damaged my battery. Ideas?

Yes you may damage your battery. At 0%, there is still a small buffer remaining, however even small peak loads may cause a voltage drop below 3 volts/cell which will cause an irreversible capacity loss, even if the drop is just for a couple of seconds. If you want your batteries to last long, never fly it lower than 20%. This leaves the battery with enough remaining capacity to withstand a sudden power burst, eg in a RTH maneuver.
