Hi all,
I'm running a 12S pack with R/C ESC controller with a servo tester throttle. To turn on the ESC, I have to manually plug in the anti-spark cable (a resistor to slowly charge the ESC capacitors) and then plug in the main battery power to the ESC. I'd like to just use switches for this step.
Are there low resistance power switches out there that can do this job? I don't expect it to handle the capacitor charge spark. I still expect to have two switches: a small one for anti-spark and a big one for main power.
So my plan is this:
One small switch with resistor in line to handle the initial ESC capacitor spark. This gets switched on first.
One large switch that connects the main battery power to the system
My question is, what kinds of switches can handle high power like this? It's roughly 48V and 50+ amps peak. I'm looking for low resistance, similar to the 6mm bullet plugs I'm using. I've looked into contactors, which seem like high-power relays, but this require constant supply of power to stay on. Are there any regular, mechanical switches that can handle this?
Any advice or pointers would be appreciated.
