This is an universal DIY 12V Battery Pack. With the additional Bluetooth Amplifier board screwed on top, it becomes a great, very compact technical package for a speaker built. (You'll just need pair of speakers)
It is made out of 3 18650 Batteries which are connected in Series. The special thing about this Design is, that you can just exchange the Batteries when they lose their capacity or when they are broken. This wouldn’t be possible with soldered Batteries.
The Bluetooth Amplifier I am using here is the TECNOIOT YDA138 Bluetooth Amplifier Board Module 2.0 Stereo Class D 2 * 15W DC 12V 2A
You have to print 3 Parts:
- Cover_Amplifier_SLA_FDM.stl
- Main_Body_SLA_FDM.stl
- Lower_Shell_SLA.stl or Lower_Shell_FDM.stl
(depends if you have an SLA or FDM Printer)
What you'll need:
- TECNOIOT YDA138 Bluetooth Amplifier Board Module 2.0 Stereo Class D 2 * 15W DC 12V 2A
- 1x ILS 3S 20A Li-ion Lithium Battery 18650 Charger Piece B BMS Protection Board 12.6V Cell (availabl
