  • So nice having a second battery for my JBL Stage 320!
I highly recommend getting this back up battery. You never know when a battery could start going bad. Also it's wonderful to be able to swap out the dead battery with a full one to keep the party jamming. Only wish there was another way to charge them rather than only when installed in the speaker. Hope JBL will make a portable battery charger. ... show more
