HI all,
When i connect my last positive to the battery it always sparks and it’s not a small spark. Everything is disconnected from my load except Orion, BMS and battery protect. When i disconnect and connect again in few sec no sparks.
Is that normal or i need to worry about something, everything works but that spark is giving me concern and it shouldn’t be that big. (shunt is showing 0 amp draw so there is no load)?
