Roland BTY-NIMHA Rechargeable Battery for Roland Amps
The Roland BTY-NIMHA Rechargeable Amp Power Pack offers a convenient reusable power solution for select Roland mobile amplifiers that support battery operation. This includes the CUBE Street EX, AC-33 Acoustic Chorus, and other models. The one-piece design pops easily into the back of the amplifier, eliminating the need to fuss with multiple AA-size batteries.
Furthermore, the benefits don’t stop there. With this battery, you also get up to twice the runtime over standard batteries, and the amplifier delivers output power and SPL that’s nearly equivalent to using the AC adaptor.

- CUBE Street EX Battery Powered Stereo Amplifier
- AC-33 Acoustic Chorus
