I already know the Optima 6 does not have the Data Port for telemetry, however;
Does it still have the SPC port, and does it send the SPC voltage back to the transmitter?

send back = telemetry, so no such feature, sorry

The battery voltage telemetry is built into the receiver/module so you would get the receiver voltage even withthe Optima 6.

Sorry, don't understand, there was stated that telemetry as whole is not a feature of Optima 6, not data port only...

It does not support the add on telemetry features but does still have the receiver voltage telemetry function.

Brendan, with the Optima 6 will the Aurora 9 only show you small receiver pack voltage or can it show you 3+ cell voltage for an electric aircraft flight battery?

Optima 6, like big brothers 7 & 9, sends SPC Voltage to the Aurora screen in lieu of that of any battery plugged into servo side of transceiver.

My apologies for resurrecting such an old thread but I can't fine any answers. I just ordered the Aurora 9 and was wondering if there's a way to receive the battery voltage if using only one receiver battery? Can you make a Y-cable and connect to the SPC port with positive/negative only?

Is there any way possible to use one RX battery and get the voltage info sent to the Aurora 9?

SPC does not control the battery telemetry, it is simply one of two methods in which either the transceiver's
EP power pack or a GP battery supply voltage can be returned.

Please refer to:

...Low & High Voltage setup, Current Draw/Amps - Warning: Never use Balance Taps - Video

. Optima Transceiver (RX) - EP Models Use SPC Port for RX Power Supply (BEC only is unreliable) & correct Battery Telemetry.

OK, so if on my GP model, if the RX battery is plugged into the side that controls the servos, I'll still get the battery voltage displayed on the transmitter?

There is You Tube video that shows how to get both receiver and motor battey readouts on an A-9 screen using an on board current sensor and telemetry return device. Don't ask me how it works.

But you can not do that with an Optima 6.
Optima 6 will send you the voltage of either:
a. whatever is plugged into the SPC port

or

b. The voltage feeding the servo rail If the SPC port has its "bind connector" in
