Hey guys Im trying to convert my dual 18650 parallel box mod to series, I was needing to know what I can salvage, what I need to get and how to convert it. I want it as simple as possible. I have the box itself, sled, mosfet, firing switch, 510, and the wiring inside the parallel box, also the box is a purely simple Hammond 1590B with no volt meter or lock switch. Thank you for your help
