Voltage Sensor?

[RC_Hobbyist]

I have a FGR4S receiver which came with my Flysky NB4+ transmitter.

I am going to get at least get a temperature and speed sensor modules at the minimum,
but I was also considering a voltage sensor for the battery.
The transmitter itself has a RX voltage monitor built in, so if the car goes slow or otherwise stops
dead in its tracks, I will know it is a low voltage scenario to the receiver.

Given the scenario above, would adding a voltage sensor be redundant in my case?

There are some scenarios where such a device would be useful, such as in endurance racing to alert you to the need for a pit stop for example, but for normal running it would be redundant. Your ESC should take care of your battery by cutting off before it reaches an unsafe level of discharge, and the fact that your car has stopped running should alert you to the need for a fresh pack.

That isn't to say you shouldn't fit one though. Some gadgets add value to the hobby simply because they are fun or interesting. They don't need to be useful to be worthwhile.

I won't be doing much endurance racing with my TT-02 Toyota Yaris WRC car
But its good information to know.

As a side note, I have ordered the temperature and speed sensors.

I have two HotRC CT-8 which I love as they have voltage information. Really handy for information. Only thing is that is a bottom budget unit, so its voltage warning cannot be set from the default 7.3v. I like to run my batteries to 7v and it just keeps beeping its warnings to me for the last 0.3v.
