For Lormax/Harley/8avgmpg, have you guys ever tried to upgrade the on oars charging module in the Karma? Is it a bespoke unit just for the Karma? I had a faulty diode in the charging system and it burned through 2 OBCMs until they were able to fix the root problem. Just wondering where I will be able to get a replacement unit if that gives out (also wondering if its possible to swap out for a 6.6kw unit to charge faster?). Thoughts?
