This video is a short tutorial that present two ways to display the battery level on a TX16S transmitter running OpenTX.
00:00 - Short Introduction
00:38 - Displaying the battery level as a value
02:26 - Displaying the battery level as a progress bar
MORE INFO:
1. In this video, I have Li-Ion. If you search the net, they consider that 3.0V must be the cutoff at room temperature. But, you go to the outside where can be wind and low temperature - the winter is coming 🙂. So, I decided that to take a more conservative value of 3.2V. I have 2 elements, so I choose 6.4V.
2. If you use a Li-Po battery, the voltage must not be below 3.5V per cell. Even so, many recommend not being below 3.6V. In conclusion, if you use Li-Po use 72 as a minimum value.

Nice video, thanks for posting. I searched on RU-vid all day long but I was not able to find a tutorial on how to read out the value of the S2 knob... That said, I have my gains for the S6R set on the S2 knob and would like to look at the plane, and not on my screen, while turning the knob. So it would help if my TX16s would read out the value for me. Any ideas!? Thanks.

@i3Drones 2 месяца назад

You can use some thresholds, then your knob reach a such value it will trigger an audio warning.

@andresmaturana8310 2 года назад

Excellent video! Just one question. Why sis you select 64 as your lower value? Is 6.4 volts the completely discharged value for these batteries?

@i3Drones 2 года назад

If you are using a LiPo battery, the voltage must not be below 3.5V per cell. Even so, many recommend not being below 3.6V. In my case, I have LiIo.

@witneydiggersrc3251 8 месяцев назад

Great video. You show an arrow to point out two battery displays, one that the TX16 shows by default. I presume you have to have both and that default cannot be changed or removed so one widget remains?

@i3Drones 8 месяцев назад

I'm unsure, I will go to my station to test ... but I think it is impossible to remove.

@i3Drones 2 года назад

@@LordFpv, I have little experience with EdgeTX, but having in mind that EdgeTX is a fork of OpenTX they are similar. So, if in battery metter range you have 3.2V and 4.2V - put 32 and 42 values on the widget.

@@i3Drones Thanks,that i think but i am not sure so i need to ask :) Thank you :)

@GaryRushton 3 месяца назад

Excellent👍. I wondered why the original setting is 1024? Seems 64 and 84 is a big reduction Does it make a difference if you use lipo batteries or other types and is this what 1024 represents? 🤔

@i3Drones 3 месяца назад

I think 1024 is maximum resolution accepted. They use a analog to digital convertor on 10 bits.

@user-mq2ok5bt2i 2 месяца назад

what should be the voltage read when it is low and time to charge the transmitter? also what does enable maximum throw on one of the model setting does? when i enable it for some reason the throttle comes on while throttle cut switch is on

@i3Drones 2 месяца назад

The lower voltage depends by battery types. For LiPo is 3.6V (you can go down to 3.5 but not lower) for LiIon is 3 V. If you use a discharge rate below 1/2 of the C rate, then 2.75 volts. BUT 2.5 V should be the absolute limit.

@i3Drones 2 месяца назад

The second part of your question I was unable to understand.

@user-mq2ok5bt2i 2 месяца назад

how do yu have your timer set up, mine is way too small and do you have count remaining?

@i3Drones 2 месяца назад

You have 3 timers - into TX16S. Activate one of them and you will have te same information like in my case.

No, this is a global setting - you are not doing something special at the level of a specific model. So, it works with all your models.

@chrispirvan4969 Год назад

While this works for the TX battery, it doesn't work at all for the main (flight) battery, at least not for me. I have Telemetry on my ESC/FBL, which shows the main Battery as RB1V. I can set up a value widget, select RB1V for the source, and I get the current value (eg. 23.9V), but if I choose a Gauge widget, select RB1V, It defaults to 100%, regardless of the values I enter for MIN and MAX. I tried 210 ~ 252 (21.0V to 25.2V), and it always says 100%. So what's the trick to get a percentage gauge for the main battery?

@i3Drones Год назад

In this evening, I will make the same setup on my Crossfire - base on the battery from the drone. I will give to you a correct answer in few hours.

@chrispirvan4969 Год назад

@@i3Drones Yes, I'd like to see how you do this, because I didn't work for me. I had to get a separate widget from Github to make it work, but that widget is large and can't be put on the top bar

@i3Drones Год назад

@@chrispirvan4969 in my case (Crossfire system TX + RX) the RxBt (receiver battery voltage from telemetry) works very well with Gauge widget - as expected. Second, I converted RxBt = {21.0V to 25.2V} => y = {0% to 100%} by using y = 23.8 x RxBt - 500 and I tray to implement this relation in OpenTX in order to print the result in a Gauge widget - without success. So, right now I am without any ideas for your problem. I have a question: Does not RB1V means reference battery 1V? In this case it is normal to display all the time 100%.
