Yes.

Now take the black wire that you have in your hand here:
This is the battery power wire.

You will have to cut off the connector from the battery power wire.
Then crimp on female 'bullet connectors' because thats the type you have on the controller.

Remember: It does matter which which wires you connect to which. Only ever do: red to red, black to black.
If it is not clear which is which inside the battery power wire, then do not connect them. Also before you do anything, turn off the battery, or disconnect the battery from the battery power wire.
