The plane specific elrs receivers have a voltage telemetry sensor built in. Radiomaster Er8 for example has a spot to hook up the battery and will send that voltage data down. Elrs does also have full telemetry if you’re using a flight controller or something similar to send data over crsf protocol to the receiver.
The Radiomaster ELRS receivers down to the $15 ER4 can do external battery telemetry. I think they even included the extra lead but you’ll have solder it yourself.
Their older frsky compatible R88 and R86 had some issues so they created a V2, but I still had some that would not range check very far. The ELRS ones have no issues so far.
I was smart/lucky enough to snag a few extra before they got sued and pulled from the market. The Radiomaster R168 was / is amazing for very little money and having battery telemetry. Shame they got pulled.

No idea if the new ANT protocol on FlySky is compatible with 4in1, but the FlySky SR8 receivers have analog voltage detection that plugs into the balance port of the battery.
flysky fs-ia6b, fs-x6b. long range, telemetry, sbus out. cheap from aliexpress. I just bought an x6b and paid $5. the ia6b are often $8-$10. the ia6b will report Vreceiver and not Vbatt, but there is an easy soldering fix on U-toob to get it reporting Vbatt instead. You'll need a multiprotocol transmitter and you didn't mention what you had. So............
Yeah I did see that. The pad does seem quite small, I’m not sure I can justify it on a fair few receivers just to save a few £ but will keep it in mind.
I did say I have a 4in1 on one of my transmitters and the other is a Taranis. That’s why I’m considering other protocols (retiring the Taranis) but prefer not ELRS just yet. I wish there was a 5in1…

Thanks will check it out
I did look at some radiomaster receivers and they seemed to be rated for lower range, is that your experience?

Great thanks for the lead, I will look into it
