Hello to all,
first time that I’m in this forum.
I just started my copter career with the 3DR APM 2.5. Yesterday I did the first short and successfull indoor flight with it and my quadx. All looked fine for the first flight.
Today in connected the Lipo again but the receiver showed a voltage of only 4.69V. No arming possible. I connected to USB as well and it raised to 4.8V, still too low.
The only thing I did yesterday, was to attach a Lipo warner by solding it to the power distribution board. I detached it today, no change
A maybe helpful information… Powersupüply is throught an ESC, means JP1 is set.
Any help?
Thnaks
