Boss BTY-NIMH/A Rechargeable Amp Battery Pack

The Rechargeable Amp Power Pack presents an efficient and reusable power solution tailored for specific Roland mobile amplifiers compatible with battery operation. Notable models encompassed within this compatibility include the CUBE Street EX, AC-33 Acoustic Chorus, and various other compatible amplifiers. The integral design seamlessly integrates into the amplifier's rear panel, obviating the necessity for managing multiple AA-size batteries. Beyond this simplification, the advantages extend further, yielding a runtime that can extend up to twice the duration achievable with standard batteries. Moreover, the amplifier maintains output power and Sound Pressure Level (SPL) performance that is nearly commensurate with utilizing the AC adaptor, thus ensuring consistent and reliable operation.
