Step 22: Wire batteries up. These being expensive batteries I want to make sure they are protected from damage. A battery management system (BMS) is employed. A gracious EV-cohort donated an Elithion BMS needing only minimal additional components. This BMS monitors voltage and temperature and disables the drive if a cell is in danger of being damaged. It does the same during charge. This BMS uses a small circuit board that attaches to each cell, these are daisy chained together and relay data to the BMS controller. I've installed the BMS controller tucked up under the dash. I will be able to view the status of the battery pack with my iPhone and a rs232 dongle.
