Anyone got a clean breakdown of the Makita 18V battery pinout?

[Tense Tuatara]

Pin to ground in most cases. Tool applies voltage and reads the resistance of the divider to determine the pack class. Different resistances means different classes of batteries. Same approach used by most OEM battery brands.

ok so from what i gather, TH is mandatory, C1 is for balance while charging, then the +/- power pins and the 7 ID pins which are mostly resistor coded to each battery class. Did i get that right?
