I purchased a non-working Vectrix electric motorcyle and removed the existing battery packs, replacing them with Lithuim packs.  Have riden the bike for two years now but have been managing and balancing the batteries manually.  It's time to develop a safer system for active monitoring while riding.  Monitoring system will be a single board computer, Beagle or PI (SBC) communicating to an I2C bus multiplexer that communicates with 6 AFE IC's.  System will allow for monitoring of 72 cells in groups of 2x6S.
