Sanwa m12 voltage issue

[Mx45]

Hi just seemed to of found an issue with my Sanwa M12 it shows the incorrect Rx voltage I'm running the correct reciever as supplied with Tx and I am using the telemetry to keep an eye on voltage and motor temps, however the display seems to only be showing Bec voltage and not battery supply voltage yes I'm running it with an esc (tekin rs pro) can this be rectified or am I wasting my time. Many thanks in advance.

Which receiver are you using. the usual receiver that come's with the m12 is 471 this is not telemetry receiver.

Hi I have two receivers one is the 462 telemetry version and I also have a 471/2 all I want to do is get pack voltage not Bec voltage on my telemetry

I'm not sure you'll be able to. I don't have the telemetry receiver, so some of what I'm going to put below is semi guess work.

Look at it logically:

The receiver is what transmits the voltage to the M12, so it can only transmit the voltage that it knows about. It knows about the bec, as it's what powers is, so that's what it will send. It would need a direct connection to your drive battery to know what the voltage of that battery was, and I'm assuming it doesn't have this.

Hi it seems the Rx 462 has a pack voltage wire on it that you connect direct to the pack it has something to do this running these in nitro rc and not electric, however the rx461 and rx462 look identical apart from this extra positive supply. I did read that you should be able to take out the esc red wire out of the plug and then run power direct from pack to Rx

I'd say if you are not sure be very carefull there very expensive to replace.
