I charge them separately as we only have a 6S charger. When you look at the maths, the LED strips draw 400mA over 1m and I am using less than half that. 200mA in comparison to the idol rating of the motor 2.24A its less than a 10th, and the draw when its spinning the weapon its probably nearer 20A so 100th. In 3 minutes I can't see it off balancing the packs enough to damage them.

Anot other thoughts from people? Have I missed any options?
