Something I've not quite understood yet: what's to point of large parallel connection in ebike battery packs ? From what I understand, series is where the juice flows. The only current flowing in parallel (besides both terminals) would be balancing current, which is very small.
=CELL1==CELL2==...==CELLN= high current flow
I low current flow
=CELL1==CELL2==...==CELLN= high current flow
.. and so on
The scenario in which large parallel connections seem to make sense, is in the case one series connection breaks - for one reason or another. The flow would than be redirected over the parallel connection to the remaining series. But in that case, wouldn't it make sense to use the parallel connection as a fuse, and disconnect the faulty series to save the other ones from overcurrent ?
