Universal Rechargeable Battery Pack Review

Must have

If you are installing the active pickups this is a must have no more 9 volt batteries and can charge with the supplied cable, after you drill the hole in the back cover.

Very EZ & Very Handy!

So, I am doing a custom Jazz Bass with EMG X Series 35TW-X-R and 35DC-X with the BTS preamp/EQ. Recommended to run @ 9v, no benefit to run 18v with this system. Just like the Fluence systems. I decided to go all in and not have to change batteries, have a 9v go wrong and make a mess in my Bass nor have to shell $5.00 a pop to change over the life of the Bass. Also, ALWAYS operating… read more at full power, because I will keep it charged! I had just gone to the Eventide PowerMax with a USB power out for my pedal board. Now I can just run the charging cable off that when I finish for the day. Nice item that's easy to install.

Ditch the 9V batteries

A+ to Fishman on the rechargeable battery pack, easy to install, looks great, works perfectly. The fact that it also works with any active pickups is a huge bonus as I'm actually swapping out the Fishman Moderns that came in my guitar... (I know barbaric, but what can I say, I'm not sold yet and now my inner tone demons are battling it out over Duncans and EMGs). My only two suggestions… read more are rewiring the original 9V battery clip leads to a JST connector and leave it unplugged inside the cavity. It'd be a shame if just before a show you realize you forgot to charge the battery pack or if it fails for any reason, it's definitely better to have the original 9V leads as backup! Second is buy yourself some dust covers for the micro USB.

Very cool - integrates with existing systems

I have a music man JPX 7 with piezo system. I added a set of Merrow Fluence pickups and added the rechargeable battery pack too, which was surprisingly easy; I clipped the + and - wires of the existing battery supply in the guitar, and joined then soldered the red (+) wire to the red from both the fluence pickups, then soldered these to the + from the battery pack. Then took the… read more existing black (-) wire and soldered this to the battery pack white wire (-), and finally soldered the ground (black on battery pack) to the back of my volume pot and voila! Fishman does state that I'll get less playing time per charge as the piezo is wired in too, meaning 100-150hrs playing vs the 200-250 with just the Fluence pickups. We'll see though, as the piezo system is only turned on when the 3 way toggle on the guitar is engaged for piezo, and the regular alkaline battery never died this way
