This is one method for preventing or reducing the "pop" when you connect a high voltage lipo battery to a HV ESC (6S+). While hearing the "pop" is good, according to some, it is bad for the battery/ESC connector since the "pop" leaves a nice pitted and carbonized spot on the tip of the first contact point. This, (and it will get worse with each use), will cause a voltage drop across the connector. This will rob you of power and may even damage the power system. Using the Anti-Spark Wire in the manner I show here, prevents the corrosion of the main battery contact. If any pitting occurs, it is away from the main battery contact on the connector.
I also show how the Anti-Spark Wire (ASW) is used. Touch, hold, and release. That part of the video applies to ANY ESC equipped with an Anti-Spark Wire (either added by the manufacturer or the user).
Next question asked will be "WHAT is the value of the resistor?". According to Castle Creations, you should limit the value of the resistor to 1 ohm (I use 1 ohm, 1 watt, flame-proof resistors). This allows the microprocessor to correctly start up, and to allow the processor to determine automatically, the number of lipo cells.
I agree with this value for any ESC. With the method I use (the hole in the side of the connector), any pitting (or "popping") that might occur is limited to the side of the connector away from the main contact point of the connector. That is desirable, as the main contact point retains its conductivity. If the manufacturer happens to specify a value for the anti-spark resistor, then of course, use that.
I've seen all different values posted on the internet and in print, from 10 ohms to 50 ohms, most commonly. The Turnigy dLux ESC shown in the video uses a 100 ohm resistor, but keep in mind that you have to program the number of lipo's the ESC is to be used with, as this ESC has no Auto-Lipo cell detection.
