    Hi,
    First post. Im working on a portable boombox powered by a 4s 18650 li ion battery pack. The pack is going to have a PCB protection. I need one more protection that cuts power at 3.5v and found a guy on youtube doing this in a smart way. I copied his idea and added a small balance charger bought from hobbyking. If you look at the image. Is this going to work or do I need improvements? Answers are always appreciated :)
