My Victron 30 amp DC-DC charger is showing 15.2 volts output while the engine is running (input voltage is 14.2 volts). This is higher than expected. This charger's input is the house batteries and both the house and starter batteries are connected to a Victron FET to get charged while engine is running. When the engine is not running, the output voltage is typically in the high 13's. Is this ok to have 15.2 volts going into the battery and if not what action do I need to take. Thank you, Pat
