Spektrum telemetry, 4651T receiver, HW esc: No BEC voltage

In case you do not know something or you are not sure, here is the right place for your question.

Hi,
it seems that Spektrum 4651T and Hobbywing platinum V4 esc‘s don’t send values of the BEC voltage in Spektrums telemetry system. Is it possible in further firmware versions, the Spirit unit sends its BEC voltage instead of?

Hi,

HobbyWing ESCs are not sending BEC voltage with telemetry at all. So technically it can't be implemented in any way, until HobbyWing will allow it. But I fear there is no voltage sensor for such purpose. But with different ESC it can work.

MSH Brain inserts the BEC voltage measured by the FBL unit in this case.

I suppose this could be easily done by Spirit, too, since it measures the BEC voltage?

The voltage can be measured only by receiver itself. There is special pin designed for measuring analog values. Some Spektrum receivers are doing so out of the box for BEC voltage, but I am not sure about 4651T.

I meant that you can easily send the BEC voltage which the Spirit FBL itself measures. Just send it via SRXL2. Either enter it in STRU_TELE_ESC (voltsBEC) or in STRU_TELE_QOS (rxVoltage) ...

That's how e.g. MSH Brain enters the BEC voltage for ESCs / RXs that do not provide it.

No, it is not possible. Spirit FBL is not measuring voltage in that way and I can't comment about other brands.
Only Spirit RS is measuring BEC voltage and other variables in full extent and sending through telemetry.

Ok. Thank you for your answer.

I hope Spektrum will add RX voltage in further fw versions of the 4651T, like the old TM1000 was able to do it.
