Will this attempt to provide 20 volts when the input is lower, or will it only negotiate an output less than the input?

It's buck only, no boost. So same or less than input voltage.

Do i need to use a seperate C2C cable for each voltage or does this work with different devices allowing them to negotiate their own power?

Device negotiate the voltage, also it's one directional, meaning you can not charge the battery it's soldered to, you'll need another circuit for that.

Why does it keep turning off? I'm using a 18 volt drill battery. Starts off charging just fine then shuts off after about 15 seconds. Anyone know why?

Have you checked to see if your solder points are good on the board
