Yamaha THR - Rechargeable Battery Holder

thingiverse

This replacement battery holder fits the portable Yamaha THR line of amplifiers, specifically the THR5 and THR10. The THR10C model was the main focus, but this design replaces the standard 8xAA battery holder for any amplifier in the THR series. With this modification, you can use your amplifier on-the-go without needing to swap batteries. Simply charge it up using the micro-USB port at the bottom, and with a good battery, expect over 5 hours of playtime. The design features an openly mounted battery, allowing for easy charging from outside and swapping out old 18650 batteries when needed. Feel free to share your printed results!
