The pinout on the Porter Cable 20V batteries doesnt get talked about much, so figured I'd toss in what I found into the thread for anyone else digging into these pack.
The standard layout for these batteries are as follows:
is the obvious positive terminal (for power)
is an obvious negative terminal (for power)
ID is an identification pin for the tool to recognize the battery as the correct and legitified product
TH is a thermistor pin to allow the tool to monitors the temperature of the battery
C1-C4 are junction pins for each of the 5S battery cell group to allow the BMS to balance each group individually
