I upgrade the battery life on the JBL Encore Essential (and why you may not want to do the same)

I did not intend to make a video for this but I had a camera on hand and decided to record. I did not put much effort into the filming process and unfortunately some steps were missed. After doing this video I decided to try and add two cells and place them in the compartment with the mainboard. It worked exceptionally well.
