. Introduction
This project consists of creating an adapter that allows you to extract power from a Festool battery to supply circuits or electronic projects. The base is 3D-printed in plastic and uses two screws to make electrical contact with the battery terminals.
2. Project Objective
The goal is to make it easy to use a Festool battery as an external power source, especially for testing, portable projects, or repurposing unused batteries.
3. Required Materials
One Festool battery
Base printed in PETG or another heat- and impact-resistant polymer
2 metal screws for electrical contact
Power cables
Optional connectors (XT60, banana plugs, etc.)
Tools: screwdriver, soldering iron, 3D printer
4. Technical Description
The base is designed to fit the shape of the Festool battery and provide mechanical stability.
Two metal screws are positioned precisely to contact the + and – terminals of the battery.
The screws are connected to output wires to transmit voltage.
Proper electrical insulation is essential to prevent short circuits.
Space is included to optionally integrate a fuse or switch.
5. Safety and Precautions
Always check polarity before connecting.
Never short the terminals.
Add protection (fuse or circuit breaker) if the adapter will be used for extended periods.
Use a durable plastic such as PETG, ABS, or PC (polycarbonate) to prevent deformation or weakness.
6. Possible Applications
Arduino/ESP32 projects requiring mobile power
Testing 12V–18V motors or modules
Backup power supplies
Portable DIY electronics

8. Conclusion
This adapter is a simple, effective, and low-cost solution for using a Festool battery outside of its original tool. It provides great flexibility for DIY projects and helps give powerful batteries a second life.
