Oof... Thats pretty low to be starting at. The lowest I have took off with my aircraft was 60%, but even then those occasions are rare. The issue I can probably see by taking off at such low percentages is the fact that the readings can be incorrect, so for example, I had my car in cold weather read that it was at 14 volts when turned off, but it wouldnt start due to the gauge not reading true. This can relate to drones as a drone at rest, i.e. not flying does not use the same amount of energy as when it is in the air. As people have mentioned above, what most likely happened is a cell failure due to overdraw or flat out losing enough energy to essentially brick the battery. More than likely due to software in the battery preventing the cells from getting too discharged, thus creating a failsafe that prevents other cells from getting damaged or causing other issues when charging and or flying.
TL;DR Your battery probably bricked due to low energy in one or more cells, causing a trip in the software/hardware of the battery preventing it from being charged. I have never had this happen to me personally but it makes sense from an electrical standpoint, given the nature of these batteries. |
