Step 3: Connect the battery pack Once the power supply has been removed, you can connect the 3s 18650 lithium battery pack to the Boston BA635 system. Solder wires from the battery pack to the appropriate connections on the system, making sure to connect the positive and negative terminals correctly.



Step 4: Install a power switch To turn the speaker on and off, you'll need to install a power switch. Drill a hole in the case of the Boston BA635 system where you'd like to place the switch, and connect the wires from the switch to the appropriate terminals on the battery pack.



 

Step 5: Close up the case Once everything is connected, you can close up the case of the Boston BA635 system. Make sure that all of the wires are securely connected and that there are no loose components inside the case.








Step 6: Test the speaker Before you take your new portable speaker out for a spin, make sure to test it out. Connect a 12V DC power supply to the system and turn it on to make sure that everything is working properly.

Conclusion: Building a portable speaker with a Boston BA635 system and a 3s 18650 lithium battery pack can be a fun and rewarding project. By following these steps, you can create a speaker that you can take with you wherever you go, and enjoy high-quality sound no matter where you are.
