## Description

From the manufacturer BTY-NIMH/A Rechargeable Amp Power Pack The Rechargeable Amp Power Pack offers a convenient reusable power solution for select Roland mobile amplifiers that support battery operation, including 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. But the benefits don’t stop there—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.* *Up to twice the runtime is possible compared with eight AA NiMH batteries with 2,450 mAh capacity. Actual runtime and performance can vary with the conditions of use. Official Roland Rechargeable Battery Pack for Select Amplifiers Easy to install and remove Longer runtime than using AA batteries Allows the amplifier to deliver more output power and SPL Premium design with safe, efficient, and reliable NiMH battery Can be charged with the AC adaptor included with supported Roland amp models Compatible Products CUBE Street EX The AC adaptor included with the amplifier can be used for charging. AC-33 & AC-33-RW Acoustic Chorus KC-220 Keyboard Amplifier BA-330 Stereo Amplifier Optional PSB-12U or PSB-12U2 adaptor required for charging.

Review: Dies if you discharge it. £100 disaster. - To quote the manual "In the event that you leave the amp on after use and the battery keeps discharging, the battery may over-discharge, causing the safety protection circuit to activate. The battery cannot recharge in this case." I tried, "Try unplugging and plugging the adaptor into the DC IN jack several times." again, as per the manual, 20 times, no joy, still dead. I'm thinking that I should have bought Duracells. When I plug it in, 2 LED flashes, then dead. When I unplug it, 1 LED flash after 2 seconds then dead. Unplugged and then plugged in again, quickly, BEFORE the single flash...it started charging. £99 battery...relief!. I really struggle to believe that this design got through any kind of project review, at any stage. Yeah, it works as a battery. It lasts quite a long time. If I forget to turn the amp off next time, will it still recover? I have a bit of Roland/Boss kit. I had an unqualified high opinion of Roland/Boss up until this point. If you never, ever, forget to turn your gear off, this is for you.. If your battery won't charge, I hope that this works for you.
Review: Essential Component - This is a clear step up from operating your Roland Cube (mine’s an AC33) with regular batteries or trying to source AC mains, especially outdoors. Looking very neat, it attaches in place of the battery tray supplied with the amp and can be charged in situ, although the amp may not be used when charging. This battery pack delivers sufficient power to enable the amp to produce almost the same output as when using AC mains, which is a big bonus. It also obviates the need to fiddle around with the adapter and eliminates the need for a long extension cord on gigs. Overall, my calculations suggest that in the long run this is more economic than using regular cells, although for me the sheer convenience makes this a must have accessory.

*by A***R on 2 August 2024*

Battery pack fails to take any charge from the standard Cube Street EX PSU. Minimal user documentation provided. Unsatisfactory returns policy requires me to travel to nearest sorting office, 30 minutes away.
