The Frsky Series: Setting up One or Two FLVS ADV Voltage Sensors in one Plane

Here's how to set up the FLVS-ADV sensor on your Tandem Recruiter and X-20 Radio. This applies to Access receivers and the other Tandem receivers and transmitters as well. I also show you how to hook up two FLVS-ADV sensors for 12s setups.

Some of the menu options have evolved (in particular the play value configuration) but still a very helpful video, thanks!

[@petetynning9964]

Very Nice Video, well explained and you were very thorough

[@michaelhollingworth8905]

Very good, easy to follow video. Thanks.

[@jeffjackson6358]

Where were you a week ago? I figured it out with Lior's help and Facebook. I love the two voltage sensor option on my HSD ME-262. Thanks for all your videos, love them!

[@janmatejcik7073]

This hepls me a lot! Thanks!

[@turbinematt3646]

Very good video! Set one of these up a month ago but no alarms yet. I will be referring back to your instructions when I get ready to set them up. Nice work! Thanks!

[@all_rc]

Glad it was helpful!

[@ninosaviation]

Nice video. I set mine up to look at the individual cells rather than the total voltage. I set it to warn me if any cell goes below 3.60V with a time delay.

[@zilog-z80]

Very good, thanks

[@stevendeweerdt1207]

Thanks for the great video, the multi-lipo calculated sensor tip will make battery management much easier. Strange that the S-Port on the receiver doesn't work get your stuff together FrSky.

[@MikePilot72]

Make sure that your Tx and Rx have both been updated to the latest firmware or you may have issues finding the Lipo sensor.

[@all_rc]

Yep, true. I did a video on updating firmware on sensors, receivers and tx for those looking to learn.

[@briandodds]

Fantastic video! Learned a lot! If you change the sensor ID and then you move it to another receiver later will it stay changed?

[@all_rc]

It's been a while since I tested that but I believe it will. The id stays with the sensor if I remember correctly

[@briandodds]

@@all_rc I wonder if I can do this with two of the 40A current sensors also.

[@all_rc]

I don't see why not. I haven't used the 40a current sensors but the 160a sensors work the same way with ids

[@davidhall4398]

Brilliant video ..about to purchase a new Tx .... Can you setup vibrate on the Low Voltage alarm so i can listen to music via Bluetooth headphones?

[@all_rc]

Yep! Go through the same process to set up the alarm but under special functions, instead of PLAY VALUE, choose HAPTIC. Everything else is the same. Give it a try. If you dont get it working, send me an email at [e-mail] and ill do a step by step for you.

[@davidhall4398]

@@all_rc Thank you so much for your fast reply...can you use the X18/X20 with a SIM through the usb cable?

[@all_rc]

You should be able to but i honestly haven't tried. I use my old radiomaster radio for sim. I might give it a try and if it requires more than just plugging it in, i might make a video on it.

[@arvidbjerre30]

Great video! Are there no grounding issues with multiple sensors and batteries in series?

[@all_rc]

The sensors are isolated so no issues.

[@arvidbjerre30]

@@all_rc perfect, thanks!

[@MWXYT]

Are you sure you can use 2 sensors for 2 6S packs connected in series? With previous gen sensors this wasn't possible since they had ground connected to - of the 1st cell. Connecting 2 sensors to 2 packs in series shorted one to ground and burned traces/wires.

[@all_rc]

I've been doing it with these adv sensors without any issues. The sensors are isolated so it works just fine

[@blacksheeprcmodelers959]

great video. im having trouble adding a 3rd sensor (GPS) when i do, one of the lipos dissapears even after i changed the id of one of them.

[@all_rc]

Hmm. That's weird. Different types of sensors have different default id's so it usually isn't a problem. I have one setup with 5 or so external sensors without an issue. What sensors are you using?

[@blacksheeprcmodelers959]

@@all_rc Im using two Balance lead volt sensors and one GPS

[@all_rc]

Should work. Perhaps start from scratch. Try hooking up the gps first. If that shows up, then add one lipo sensor. Change both id's of that one lipo sensor like in my video then add the other lipo sensor.

[@blacksheeprcmodelers959]

@@all_rc ok ill give it a go soon!

[@ryansnyder7444]

If you use 2 lipos in parallel to get more mah, rather than in series to get more voltage. will you set it up the same or different from series?

[@all_rc]

I feel that the multi lipo calculated sensor is designed mostly for series setups as the lipo widget also shows total volts. If I was to use parallel batteries with two lipo sensors, I would do everything in the video except setting up the multi calculated sensor. I would have the two sensors displays. One that show lipo 1 and another showing lipo 2.

[@jeffjackson6358]

Do you have a video on how to set up "Consumption" for a voltage sensor?

[@all_rc]

Very soon!

[@all_rc]

I just reread your question. Not sure if that was a typo, but you don't use a voltage sensor for consumption. You'll need a current sensor. Frsky makes a 150a current sensor that works well for the big EDFs

[@MaxPower-zp7wy]

Why are you running down your batteries so low. 3.2V is not good for Lipo batteries.
