I recently used BLDC Motor(A2212) of 1200kv rating. I used a Avionic 2.4 GHz RZ6 Receiver and applied a 7.4V,2300 mAh LiPo Battery at its terminals via ESC rated at 30A,there was no problem in the motor.
When i increased the Supply by attaching two similar batteries in series to attain higher RPM, the receiver got burnt and couldn't be used further.
The receiver is rated as "Power supply - 4,8V to 8,4V on dedicated connector"and "Amp draw - < 40mA"
My question is does whether application of higher voltage affects the receiver as it only draws the essential voltage required for signal transmission?
And can the reason of burning of receiver be due to faulty ESC?
