So I was riding home last night after work, I was going through a pedestrian underpass (not underpower) pretty much at walking speed. I hear what sounded like my rear wheel puncturing or riding over a bursting plastic bottle. Anyway after losing a bit of power I realised id don't something stupid with the packs.
Normally I get to work and charge both packs, that day i'd forgotten to charge one so they were unevenly charged. One was full one was about half.
There is no regen enabled on the bikes controller though it is a direct drive hub motor so there my be some regenerative forces happening.
I took the Macalister pack apart when I got home and found the s3m m1c diode I bit less together than it should be smelling of the magic smoke. I placed an order for some more and will replace it and see whether this pack will charge again.
my own naïve explanation is that the regen was being taken disproportionately into the two packs and trying to charge the emptier one faster so blew that diode. I don't have a better explanation than this but I open to learning what the real issue is here.
