Motor power lead filter 3.
This is the final version with 11.6mF and a "soft start" branch with a 2.2 ohm resistor to prevent arcing at the connector. Initially, the circuit is connected through the resistor using the upper set of PowerPoles on the right. Then once the filter caps are charged, the connection is moved to the lower set of PowerPoles on the right. The user has roughly 5 seconds to reconnect before the caps discharge into the controller. Using an NTC (Negative Temperature Coefficient) thermistor might work better in a situation where the connectors aren't easily accessed, but this method has the advantage of giving the lowest series resistance after the connector is moved to the straight path. The filter now allows the PowerTap to be used without interference up to the maximum output of the motor. I removed the ferrite beads as they didn't seem to help.
