My F5085 motor (30A continuous, up to 12S) and FSESC 50A arrived, so I’m finally starting to dig into VESC and getting the electronics part working (planning to use 6S), before moving on to mechanical. I’ve done this before on an RC boat project, but this is scaled up a bit. My first question is what wire gauge to use. This should be simple enough (pick gauge based on peak current), but after doing more research, I’m more confused.
Most builds on this forum seem to be using very high current (150A continuous) and high voltage (12S+) and using AWG8 wire. This is surprising given this chart, which suggests 73A max for chassis wiring (apparently meaning that it’s a single wire, not in a bundle).
The VESC came with AWG12 wire, which is rated for 41A, which is also confusing given that it’s rated at 50A continuous. I have basically no idea what I’m doing here, so was hoping someone would set me straight.
Second follow up question is about connectors. I’d like to be able to attach/detach the battery to avoid drain. I also want to attach/detach the motor to make assembly easier. For previous project I used a Deans connector, but that was substantially less beefy equipment. Is it safe to continue using this Deans connectors, and any waterproofing issues?
Okay, last question I promise: is it safe to use regular solder for the current/voltage I’m looking at? Seems like most people go for crimping, but I haven’t got any kits to do this sort of thing. Thoughts?
