You have to remember, there are four cells already connected together in each module. Two sets of cells in series and the center tap connects the mid point of the two cells in series.
Connecting all three modules center taps, actually parallel six cells together is consider as one cell. This is the same as the manufacturer adds more plates to a cell to increase it area. This would for me to install three 180 cell BMS units.

I quite purposely did NOT parallel the center connections. This allows the BMS to monitor EVERY cell (pair) to detect problems earlier. -- Bobcats and Cougars, oh my! http://john.casadelgato.com/Pets<http://john.casadelgato.com/Pets> _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub<http://www.evdl.org/help/index.html#usub> http://lists.evdl.org/listinfo.cgi/ev-evdl.org<http://lists.evdl.org/listinfo.cgi/ev-evdl.org> For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA<http://groups.yahoo.com/group/NEDRA>) -------------- next part -------------- An HTML attachment was scrubbed...
