Thats an excellent Post. Very informative and as they say a picture says a 1000 words!
Also highlighting the pins with the red arrows/circles is very useful. I will get a multimeter at the weekend and check them out! Will be a crucial test.
And so what can you do about it if one of the batteries isnt reading the same voltage as the 2nd? Does it mean your battery is defective/ready for scrapping?

If its not the batteries then it'll be the Motors!? Very much appreciated, thanks for taking the time to compose that info.

Ultimately, i "might" still need a new battery, probably one of the 'DN' range, as my Heli (in its current setup) cant even lift my CAM !?
