Roland BTY-NIMH/A Rechargeable Amp Power Pack

The Roland BTY-NIMH/A Rechargeable Amp Power Pack is a convenient and reusable power solution compatible with a selection of Roland mobile amplifiers such as the CUBE Street EX and the AC-33 Acoustic Chorus. The one-piece design easily fits into the back of the amplifier eliminating the need to hassle with multiple AA-sized batteries.

This power pack offers up to double the runtime of standard batteries. The amplifiers output power and SPL are almost equivalent to using the AC adapter. However keep in mind that actual runtime and performance can vary depending on conditions of use.
