Hello everyone on the forum,
I have a helicopter to which I would like to add a second battery for Spirit2+Servo+RX.

The main battery would be used exclusively to power the motor with its ESC.

Introduction: Currently, with the ESC telemetry cable --> Spirit2 I have control of the main motor voltage.

Question: Is it possible to have battery telemetry with the UBEC? If so, is there a specific cable?

Thanks for reading, even more if you answer me.
