I'm also working on my rover for Magellan -- which is making more progress now that Onyx is disabled...
I have 3S LiPo power with a screw terminal out from a power switch board. I need to split it three ways. The three draws will each see a maximum of 10A, and an average draw of maybe 2A. My power cabling is all 18 gauge speaker wire. (Hey, it's cheap, and polarization is clearly marked!)
In the real engineering world, it seems like I'd get some solid copper and make some bus bars, and screw my power into those. But, I don't have bus bars, and I don't really have space, time, or budget for that.
My next idea is to parallel four two-pole screw terminals on breadboard, and reinforce the traces with copper wire, and screw my power cables into that. Except I'm all out of screw terminals after making all the power control!
So, what's a good way of splitting up battery power?
Soldering up an octopus and wrapping it in electrical tape? I don't like how that's hard to screw down well.
Using a stainless steel screw, 1/2" ear lugs, and a nut, automotive style? Do I wrap it in tape as well to avoid accidental contact?
"Euro-style" screw sockets ("sugar cubes") with multiple conductors into each screw?
