JBL Partybox 100 Battery Modification

JBL Partybox 100 uses a 4s1p configuration. I decided to expand it by dissembling the current battery pack and reusing the BMS on a higher capacity cell and creating a 4s4p. More or less everything was just splice and expanded to accommodate the relocation of the battery pack to the bottom of the unit. The previous cells were 2500mAh 10a, the newer cells are 3300mAh 10a. So it in theory went from 2500mAh to 13,200mAh. I've run the speaker for over hours and I've yet to see battery meter drop. That said remake at your own risk. I am certain there are plenty of things I would do differently if I had to do it again.
