hello to users, I ask for help in connecting the controller at zero FX 2015, the BMS is out of order in our Ukraine, it is impossible to find it, so I assembled a battery from a third-party BMS but ran into the connection SEVKON gen4 size4 80v350a can anyone tell me how to turn on the controller excluding MBB and programming the controller or no options need to buy IXXAT and DVT?
