Re: Suicide Cables Safe for Motors?

We have something we call our "motor tester" which uses an old speed controller hooked up to a chip that generates a pwm signal with a potentiometer to adjust forward or backwards at differing voltages. The main power to the motor controller is provided by a regular robot battery which we have hooked through one of the normal 120A breakers and another bus unit (I think from 2009 or earlier) with one of the 40A breakers used on the PDP.

I'm a hardware guy, so I can't really provide more details on this, but it seems like not the greatest idea, safety wise, to use direct voltage on the motor. I'm not sure there's much of a problem from the motor's perspective.
