We’re you able to resolve the issue ?
im having the same problem with basic stock BMS (i was planning on switching to the speedict Neptune)
my bike is a 2014 EM 5.7 , The solenoid tripes out after 30-60 min and now wont hold at all , I bypassed the solenoid/contactor BMS and current transformer and it charges perfectly
