DISCLAIMER: The DIY kit used does not have any battery protection circuitry and, if left on for too long, has the potential to over-discharge the M18 battery and cause it to stop working permanently.
I have no affiliation with the Milwaukee Electric Tool Corp. I am a just a fan of their tools. Improper connections may damage your battery, cause a fire, and/or serious injury.
