I'm testing my the functionality of my drivetrain (treads). I'm testing it using 2 12v SLA 50 amps batteries hooked up in series. The scooter motor I'm testing is 24v 400 watt 23a peak current. I dont believe thats the startup current though.
Anyways, I just went to test it and when I just touched the negative jumper cable to the negative battery terminal. Everything spinned correctly, but when I touched the cable to the negative terminal, it appeared as if the connection was eating at the negative terminal.
Is this normal when working with high amperages?
Could this have been because I didn't clamp it on the terminal, rather just touched it?
I just wanted to ask so I dont ruin anything.
