The Konsool/Tanmatsu battery lasts for a couple of hours and is internal to the device. This project extends the battery life of the Konsool/Tanmatsu with several hours, just by adding an extra power expansion.
Given that alle batteries are current limited by protection IC's slightly different charges in the internal battery and 18650 cells should not be okay.
Please do monitor device during charging.
- Protection IC per 18650 CELL
- On/Off switch
- Charges off the USB-C power from the Konsool/Tanmatsu
- M2 mounting holes to fasten the battery holder securely
Bonus: Use dutch police logo as Lithium ion battery fire hazard logo, because it was too perfect for that.
