| Hercules 20v Battery - Pinout? |

If that pin was a data line, and if the signal was open-collector, one could expect that the 5.1K pullup resistor would be on the receiving end. Therefore, I'm thinking that the battery is sending something to the "controller" via this pin, assuming it's not a simple thermistor. |

I bought an adapter to use Ozito batteries on Milwaukee tools, and this adapter pulls one of the extra pins to the battery 0v through a 10k resistor, and the other to the battery voltage through a 10k resistor... Not something I'm going to try on the Hercules! |

It seems like Hercules changed the way the newer tools talk to the batteries, so the adapters stopped working, and hence were pulled from sale: https://youtu.be/sdfGr3GHHMw?si=oFpk1HBI6HtltpgD |
