Hi,
I have several Milwaukee 'Red Lithium' M18 battery packs that I would like to use in a project. I don't fully understand the pinout, though. Can anyone explain the best way to connect up to these?
There are 5 pins on the battery. In the attached photo I have labeled them A through E. On both the tool that uses these and the charger, the 'E' connector is longer and makes contact first. I assume that is ground. The photo shows the voltage measured between the other pins and ground.
The battery is nominally 18 V.
The tool uses only 4 pins: A, B, D, and E. It does not connect to pin C which has a voltage on it.
The charger also only uses 4 pins, but it uses pins: B, C, D, and E. It does not use A which I measured as the largest voltage.
Thank you for any information you have on the pinout of these batteries.
