Today I just discovered a charging bug from D16 when it is too much drained out.
I left it playing overnight and charging. However, once fully charged, it stops charging and playing off the pack and will not be triggered to charge again unless I remove the cables and replug
So, I woke up with a deep discharged D16, it switch was on and it screen os black out. I plugged in USB C charger and it wouldnt have blue LED light charge indicator. I left it plugged in for 10 minutes and still nothing
I would have been freaked out by now. But having experienced this before in RC racing, I knew the packs were dead discharged. So I tool out my toolset and unplug the battery pack plugging in the D16 toward USB A 5V. It took a couple minutes and Blue LED light blinked once. This signals me that the charging circuit is healthy.
Unplugging the cables before reconnecting battery pack. Then insert USB A 5V again and Voila...!!! It starts charging.
So, just FYI, if your D16 refuses to charge due to Dead Discharge. Those are the steps to take
