I am using this with the Roalnd BA330Mostly writing this so people with a BA330 can understand how it effects that productThis would be a better review...but...**There is no way to charge this without an additional PSU if you are using it on the Roland BA330.**I ordered the PSU separately ($22 aftermarket, $45 original from roland), I am sure it will be fine, but this is not spelled out in the product description, it is listed that "you can use the original PSU". NOT TRUE for BA330.It doesn't charge while hooked into AC aka "passthrough charging" (again only testing on BA330). I hope passthrough works with the new PSU I ordered.In the box is- battery/bluetooth/amp- Right angle (RA) TRS 1/8"--> dual TS 1/4"- RA TRS 1/8" --> TRS 1/8"- RA TRRS 1/8" --> TRRS 1/8"- RA TRS 1/8" --> TS 1/4"Minor thing (not good or bad) - this battery does stick out of the back almost an inch more than the original AA pack. (see picture)So far it works great. Lasts much longer than AA battery pack. (at least twice as long)I'm super happy with it. Blue tooth works as expected. Product comes with everything you need to hook up bluetooth. I have not tried the headphone amp feature, but I can see this being very useful (routing it into wireless IEMs).

I have a Roland BA330 and this fits perfectly and gives me Bluetooth capability the BA lacks. Has about 4-5 hours life on gig level volume.

Bought this for my street/solo busking cube street ex50.Simply amazing, blue tooth a fantastic option to use the cube for a speaker music streaming or backing tracks. Tried batteries and rechargeables, they just expire quickly, max 4 or 5 hours.Last hours longer, charges faster than the AA rechargeables.I only wonder why Roland does not brand one, a clear major enhancement.Always cautious with china lithium, so far no heat buildup or fires. 😎

If you own a Cube Street Ex, get this!! It’s worth every penny! The features are very useful. It’s both a battery and amp (headphone output) and adds Bluetooth to the amp. There’s even a battery checker. All the connections are provided and you can record directly from this by plugging in your phone/pad (connecting cable provided) and using whatever app you want (GarageBand, Loopy, etc). Perfect for recording a quick jam! The battery last a VERY long time. I played for 5 hours and have barely made a dent.My only complaint is it’s impossible to find much info about setting up/using the product. The video provided by Amazon is so fast, only a hummingbird can keep up—fairly useless. The instruction card’s print is so tiny I needed a magnifier to read it. I’m not sure why this is so unknown (hardly any review on YT). I found out about it, purely by accident while searching for rechargeable batteries. It truly is a superb product! It might look pricey, but the features and convenience are well worth every penny! I’m surprised Roland/Boss don’t offer a comparable option.If you use a Cube Street Ex unplugged, it’s a no-brainer.

I have a Roland ba 330 and it says to use the original power supply to charge it. The original power supply will in no way fit into this battery. Just know you will have to buy a power supply if you want to use this for a ba 330.

I have a Roland BA 330, the adapter that came with the amp is not compatible with the cool music power battery pack, which adapter will work with this battery pack? and if you purchased one here for it, can you link the one you purchased, thank you

I use a Roland Cube EX for our group that plays at church, nursing homes and other venues. The CoolMusic came 100% charged and to date I have used for about 13 hours at the mid point output rating and it now shows 50% battery life. The bluetooth feature pairs effortlessly and is great for playing off the cell phone while we're setting/tuning up. Great product so far and I'm waiting to see how long it takes to charge once it gets to 25%.
