Fluence rechargeable battery packs are available in three different styles
Direct-fit replacements for the back/vibrato cover on a Strat.
The ideal power solution for Fishman Fluence pickups, these lithium-ion packs require no modification of your guitar, and can also be used to power other on-board 9V pickups and accessories. Featuring a current capacity similar to a premium 9-Volt alkaline battery, recharging is done via a standard mini-USB cable, which, like the charger, is included in the box.
LED indicators let you know when the battery pack is “full” and when it’s time to recharge. Complete recharge time from “empty” is 3 hours or less, and a full charge offers weeks, not hours, of playing time between charges (depending on load).
