Part 17 of a longer series on my 1978 Volkswagen Bus electric vehicle (EV) conversion (#evconversion) In this video, I show you how to wire A123 MBBs (Measuring & Balancing Boards) which includes how to crimp the JST pins and connectors. Then I show you how to configure the MMBs in the Thunderstruck MCU to lock in the BMS configuration. Then we wire and configure the TC/Elcon charger to do our first pack charge.
