Hi,
I'm working on a 12V RC car. I'd like to cut the current or the voltage to stop the vehicle automatically once the battery cannot provide more than 9 Volts.
I'm kind of a beginner at these kinds of stuff so as far as my research goes I could only find that Schotky Diodes can provide this? So I'd like to know what kind of a component can help me make this happen if not the Schotky Diode.
Thanks in advance
It's not going to be a Schottky diode but first things first. What type of battery are you planning to use and what sort of motor(s). E.g. if you're using Lipos and a brushless motor then some ESCs already contain a low voltage cutoff (LVC).

It's a 12V 7Ah, dry, VRLA Battery. I use 2 DC motors. They are brushed, 12V, 17.000 RPM
9V is too low for a 12V SLA battery, cutoff should be more like 11V.
But probably all you need is to cut power to the motors. The rest of the components will use very little power. So you can do that in code. Measure the battery voltage (use a 2 resistor voltage divider) and stop running the motors when it gets low.
