Not sure if this is the best forum for this...but it is the closest fit that I saw.

With winter coming, I want to make an "evening and night" shell for my Slash 4x4 and kid number 1's Stampede 4x4. They will be dedicated shells because we beat the shit out of them during the day and I want to reduce knocking lights off, getting them wet, etc.

I got a bunch of LED lights. Several stick on style strips, a few white light bars, a fancy multi-colour one that has a small circuit board, some individual bulbs with holders, a bunch of y-splitters (including 2 with on/off switches, etc. I have some 9v battery cases coming in this week.

I want to avoid overloading the channels on the receiver box. I have 3-4 open channels there I think. I also don't know if the 9v battery holders will fit in there anywhere, I got them just in case.

I know this question depends a lot on specifics, but roughly speaking, how much output can a single channel on the receiver box handle? Can I "y-off" like 10 times and run a bunch of LEDs off it? Or do I have to limit my "y-off" to maybe 3 times, and use 3 different channels to get the same overall number of pigtails I can connect a light to (in which case I may get more switches). I'm just trying to get some idea of what i can do here. I mean, for all I know, I can't "y-off" more than once.

If I am just using a bunch of Amazon style lights, do I need that Traxxas high voltage BEC thing?

some of the lights I got are:

In almost all receivers, the power lines (+/-) are just a connected bus that is powered by the BEC on the ESC. You're not placing any load on the receiver, just the ESC or whatever is powering the receiver.

Check the specs of the BEC in your ESC and map out the load from other devices like the servo. Another option would be a separate buck converter running direct off your main battery. With appropriate wiring/electronics, you could still control it from your receiver.

If you are worried about over loading the receiver get one of these:
