Haven't had enough time to spend on this project recently but back on track now (Was having too much fun riding my other bike, FJ1100, while the warmer weather lasted )
I've had a few problems with the cell voltage monitors. Each one consists of a microcontroller, daisychained via their own serial port. Sometimes when a relay dropped out on the bike some noise would cause the micro's to crash and require rebooting, which they do automatically, but it isn't reliable.
Yesterday I got finished testing the new configuration, which has a lot of noise suppression added to each monitor and they work faultlessly now, regardless of how much noise is coming from relays and the main controller.
The next step is to make up a set of monitors for the whole pack, install them and then clad the battery box for protection.
