Apexium DIY Battery Kit Build - Seplos BMS V2 (10E)

Building the perfect battery... almost! In this video we begin building big battery #1. This will be using a Seplos BMS with 150ma passive balancer. Challenge Accepted! We will be using the matched cells from the previous video to give the BMS the best chance at balancing the cells. I have a theory where if I arrange the cells from largest to smallest capacity this might help to create a naturally balanced pack.

Topics covered in this video include: Prepping the box, installing the bus bars and installing the cells and pressure plate.
