Here I made a 12v S4 18Ah Modular battery pack with removable cells from 18650 cells salvaged from old laptop batteries. I made a these pcbs for the Power modules, where there are glass fuses to show if any cell is shorted and can be easily serviced. I used my previously made 40cell Charging & Capacity Testing Station to know the capacity of the cells for repacking the cells in to proper battery packs.

I was contacted by JLCPCB, about their interest in sponsoring some of my projects and providing me with pcbs to speed up my projects.
