Universal Rechargeable Battery Pack

Love it!

Bought this for my Fishmsn Gluence humbuckers. Easy install. Really does hold charge for 200 hours!! USB recharge is so much more convenient that having to deal with changing batteries and keeping spares. Highly recommend!!

I purchased one of these used from the warehouse in "Very Good" condition. description indicated damage to the packaging. When I received it, there was no battery or cable. I received the charger, and the wall wart, and that's it. Apparently, somebody purchased it, took out the battery and cable, and returned it. Amazon didn't verify that all of the contents were there, and resold it. Without the battery, it's useless. I did work with CS to get it taken care of, and purchased just the battery elsewhere. The product works great, as long as you get all of the pieces.

You’ll need to solder 3 wires and drill 1/2 inch hole in the plastic plate to install. A bit tight fit in LTD SH-7 but it worked after I rotated a switch. Immediately revived guitar, Fluence pickups eat 9v batteries faster than EMG. 1 star off because of dated usb port. Come on, it’s almost 2025, it should be usb-c. And because the pcb is uncovered facing cavity it can short out on graphite paint or tall pots. Fixed with some tape, but would be nice if it was somehow covered. Other than that it works great, no complaints.

I am busy converting the second active bass to this. Long lasting charge (supposedly 120h, haven't tested), no more guessing on battery levels and randomly swapping in and out "to be safe". Just plug it into micro USB and charge until green. Note: installation requires some soldering, I had a guitar tech do it to have a clean setup.

box came unsealed and the wall charger was missing just usb cable other than that works good. just to let everyone else know this seller is selling opened items as new with missing parts have a great day.

I just wanna clear something up for anybody out there wondering if this universal remote includes the battery which it does when you buy this there are two units the one you plug into and the battery. Haven’t had a chance to hook it up to give y’all performance I will get back to you on that. Thank you for reading this.

I've got two guitars with Fishman Fluence pickups on them. I hate having to swap 9v batteries. I bought these because it was rechargeable and boasts up to 200hrs of battery life, which blows away 9 volt batteries. The install wasn't difficult, but if you have no experience with a soldering iron or active pickups it could be tricky. In use, they're exactly as advertised. I've charged up both guitars and haven't had to charge them since... granted I'm not playing hours and hours every day but I've still put plenty of hours in. I don't know about wiring for non-Fishman pickups, but I'm assuming that these will feed power to any active pickups that use a 9v power supply. VERY highly recommend!

I use this guitar about 1 hour a day and every 9-10 hours of use the 9V battery (Duracell Alkaline) must be replaced. I had to buy 9V batteries that are expensive and polluting. I installed this Fishman Rechargeable Battery system on a Fernandes guitar equipped with a Sustainer (FSK-401) that drain some current. The Fishman's instructions are clear, but I had to use the electronic diagram of the Fernandes Sustainer to be sure not to damage the electronics. Now I recharge the Fishman battery system one time a week using the included USB cable and charger (5V) in about 1h30. The steady voltage of the Fishman battery system make guitar sound more stable than before. Recommended for guitars and basses with active electronic circuit. There are also kits for Stratocaster and Les Paul guitars, which are even easier to install. Probably the greatest thing since the invention of the electric guitar !

Bought this battery pack with a set of classic humbuckers and the installation was very easy. Would buy again.
