Battery voltage telemetry mod for FlySky ia6b receiver

By default the ia6b receiver returns telemetry info showing the voltage of the receiver itself - which is not that useful when the receiver is running off a BEC powered by the main flight battery. Cutting some traces and adding a wire lets you use that telemetry for an external voltage.
The pictures on the thread were so unclear so I hesitated to do the mod... Thanks so much for making this video!
This is a great video, just what I was looking for. I have just done this mod, but I didn't bother with modifying the pin part, I just did the resistor part and soldered a pin on the other end of the wire that I plugged in to the battery balancing port (third one giving 4.16v ish). Works perfectly!!! Thank you very much.
Great mod, I've done it many times. Always tricky, I do a simplified version by running the wire from the 38.4k resistor out a small hole in the case, strain relief with a spot of glue on the PCB. No other hacks needed. The tiny resistor always falls off on me, then I connect a 39k resistor externally. Note that you don't need this mod if you can set up iBus telemetry in iNav or Betaflight! You can enable iBus telemetry using the diode/resistor trick described in iNav documentation, or using Flit10 receiver. iBus telemetry parameter 2 is battery voltage from the flight controller by default (connect FC battery monitor pad to your battery V+). In your transmitter (I use FS-I6 with 10channel firmware mod) change "Int LiPo" to "Ext LiPo" in receiver battery settings.
I did this mod to the -ia6b rx and upgraded the fs-i6 tx firmware. All is working great! The rx SMD circuitry is really small. The series resistor (for voltage telemetry sensing) cracked during mod... had to replace with 39.2 K ohm resistor. Voltage reporting is very accurate. Great mod(s)! Thanks to all for the good ideas and firmware upgrade!
Thx for sharing this - its awesome. I have only make one cut and use a jumper wire to the balancer (from the resistor). Now I am ready to fly.
Just finished this mod and worked perfectly
i know it's an old video but i did this today and it worked perfectly. Cheers.
Slick workaround and finally a useful use for rx readout telemetry voltage. I always thought that was daft. I heard the C version does this function
Thanks so much for this, just done mine at it worked perfectly. It's great with the modified firmware as it has settings for 3s, 4s etc. By the way in the modified firmware you can skip slowly scrolling through setting the alarm voltage alarms by pressing and holding the OK button in each alarm.
Thanks for sharing your knowlegde. The modification works fine with my FS-IA6B / FS-I6S.
yes that was very interesting!
The Flysky X6B receiver has battery telemetry built in, along with RSSI (great for tracking a lost model). It's smaller too but still has great range.
very useful video !! I have done in my two receivers and works perfectly with the help of Flashed transmitter with the 10-channel version, that version can set the alarm battery voltage 3s to 6s, I recommend upgrade the version of the transmitter.
Just made the cut and added the wire. Now I have a voltage telemetry I can use!! Thanks for making it easy!!
Great video. i gave a test yestorday done the mod and it working perfect
It's funny that I have a car that uses two li-ion batteries, in series they make around 7 volts so I can directly power the transmitter from there and read the voltage, no need for mod, then in parallel with the transmitter I have a voltage multiplier followed by the motor driver so it's perfect for me! I didn't know about this mod but I used this configuration to make it work. Thanks for the mod tho, very useful for future projects!
Thanks for video, it's really helpful. By the way, in FSi6 10ch mod you can set up more than 10v max voltage, even you can set up battery type and cells count.
Great help. Very appreciate your macro pictures. :)
finally tried this and it works, awesome mod vid. there must be a similar option for the non 'b' receiver too as it also downlinks the rx voltage. there is the same bank of 2 resistors... hmm :)
this is good. I have this transmitter and receiver, I have been using my no telemetry turnigy 9xr more but i may have to try this mod as the sticks as so smooth on this transmitter. You can repair the receiver antennas cheap if you find an old wireless modem router, some of them have 2.4g external antennas. I bought one from an op shop. thanks for the vid dude
