It appears that I'll be using my Duracell for the first time this coming weekend. Just getting a little nervous about a couple of things;
1) Running a single QSC K10, mixer, wireless and laptop. How long would you guess that battery will support this rig?
2) When the battery gets low on power, does it have an alarm? If it does, I need to open it up and disable the speaker.
Thanks in advance.
