BAOFENG DM-1701 USB-C Battery Shell (ABS)
A 3D-printable replacement battery shell for the Baofeng DM-1701, designed to replace the original battery housing if it becomes cracked or damaged.
This modified design also adds USB-C charging, allowing you to charge the battery without the original charging dock.
Features
Replacement for a cracked or damaged original battery shell.
Integrated USB-C charging port.
Designed for ABS printing.
Uses a 2S/3S USB-C charging/BMS module based on the IP2326 chip, configured for a 2S battery pack.
Reuses the original battery contacts.
Optional Fuzzy Skin texture for a more factory-like finish.
Printing Recommendations
Material: ABS (recommended)
Fuzzy Skin: Enable Fuzzy Skin on the exterior surfaces to give the battery a textured finish similar to the original housing. Keep it disabled on mating surfaces and areas requiring precise tolerances.
Assembly Instructions
Print both halves of the battery shell.
Prepare the original battery contacts and two Li-ion cells.
Install the USB-C charging module (IP2326-based).
Solder all connections according to the attached wiring diagram.
Insulate the connections and ensure that no exposed wires can cause a short circuit.
Check the wiring, polarity and charging operation before closing the housing.
Glue the two shell halves together using an adhesive suitable for ABS.
Important Notes
Soldering skills are required. This is not a plug-and-play replacement.
The original battery uses a 3-pin external connector, but only two contacts (+ and −) are required for powering the radio in this design. The third contact is not used.
Make sure the charging module is correctly configured for a 2S Li-ion battery pack and that appropriate battery protection and cell balancing are provided.
Safety: Lithium-ion batteries can be dangerous if incorrectly connected, damaged or charged. Double-check all connections before use. Build and use at your own risk.
