I have the 4649T receiver and a talon 25 connected to an oxy3. I have an iX12 transmitter. I have gotten all the telemetry to work but I do not get RX voltage. I read that the 4649T doesnt send this value on its own. It either has to come from the ESC or the FBL controller. I dont think the Talon 25 send the BEC voltage as telemetry. Can the Spirit send this voltage somehow?

Hello,

you have to connect pin from the SPM4649T receiver at the BEC. This pin is sensing voltage - it is wired out in the second (normally unused) connector.

Talon is sending the value as far as we know. So actually it should be visible as the BEC [V] at the ESC status page. This mean that if the ESC is supporting this, the Spirit unit will send it.

I am not sure the Talon 35 is sending the BEC voltage as telemetry data I sent a note to castle creation to find out. I believe the voltage sense port is for main pack voltage correct? If I use that to sense BEC voltage I think it will override the Talon ESC main voltage data.

The SPM4649T port has uncoupled telemetry with ESC. So you can use the measurement port for anything you like - BEC or main battery voltage or just one cell.
