I have a lithium battery, Victrom BMV and Victron Isolated DC to DC charger (12-30) on our truck camper. When the engine is running, the Victron App for the charger shows an input voltage that will trigger the charger to kick on. The output voltage from the charger reads 13.5-14v. I've confirmed these values with the Victron App and a multimeter. But there is no current flowing to the battery (which is not fully charged). The Victron BMV shows no current flowing into the battery, and I've confirmed that with a multimeter. So do I have a faulty DC to DC charger or am I missing something in the set up. The distributor (Dragonfly Energy in Reno) has been no help - they have not been answering their phones or returning voicemail messages. Any help appreciated.
