Good day !
Is it unobtanium ? Do you have one ? Looking to learn if other chargers can be used for a plain 20V XR lithium battery pack for tools. I believe there is a thermal contact which I do not know if tells the charger low or high for hot or for cold; and the ID contact, I suppose tells the charger the nominal voltage of the pack, besides balancing series-points and +/-

The Dewalt chargers do monitor temperatures, and shut off charging if the battery pack is too hot. This happens often if it is rapid charged over and over in the same day (within a few hours and after heavy use)
I use two different dewalt chargers for the 3Ah and 5Ah batteries. Seems to make no difference which charger is used for which battery, just that charging times may be different..
But, use the proper Dewalt chargers, don't try to jury-rig some other charger for those batteries.
Never seen a schematic for the chargers...

Thanks.
Am aware of precautions for charging.
The charger schematic is available on the web; what am after is the battery pack schematic.
