Hi Reuel,Thank you for this information.My eldest son is an electronics engineer so he is going to rig one of these chargers up for me (he just doesn't know about it yet}Jamesjj
I found the AU$5 Metabo IC25 charger on the shelf by chance as I often donate stuff to that Op shop near my house.
If you have not soldered 10K thermistor internally in the battery pack yet, you can still use it with an external thermistor connected from 3rd terminal to the -ve terminal.
Just rubberband or clip the thermistor to the battery outside while charging to detect the battery pack's temperature.
This charger saved me hundreds of dollars in powertool batteries.
