Our dewalt cordless drill had a broken battery which needed to be replaced. In order to replace it, we used LiPo batteries with a custom charging curcuit. In addition to this page, the discussions during the replacement can be read on github. Once done, you can find the repaired drill on the drilling table again!
Since the battery got replaced, we also needed a new charging station:
The Charging Station is nothing special just an DC to DC converter with Constant Current and Constant Voltage (CC/CV). The Current is set to 0.5A and the Voltage to 12.5V that provides safe charging process.
