- Page 2 685W Overview This Photonic Universe DC-DC battery charger is fully automatic and ideal for leisure vehicles, commercial and special purpose vehicles, boats, and any other systems with multiple batteries or power sources with an additional solar charging source. The charger operates using an adjustable three-stage charging programme and is suitable for lead acid, AGM, GEL, LiFePO4 and Lithium-ion (NCM) batteries.
- Page 3 The charger includes ports for a remote meter or a Bluetooth dongle (both sold separately), allowing data to be viewed on an LCD display or through a mobile phone app when connected. An optional external temperature sensor (sold separately) can be connected to the charger for automatic adjustment of the charging voltages depending on the ambient temperature (lead- acid batteries only), keeping the charging programme to optimal voltages at very low or high temperatures.

- Page 5 IMPORTANT! The charger requires a D+ signal to operate the DC-to-DC charging function. If there is no signal applied to the D+ terminal, charging from the source battery will be disabled and only solar panels (if connected) will be able to charge the target battery.
- Page 6 If multiple batteries are being used in parallel, connect Ss- to the negative terminal of the first battery, and connect Ss+ to the positive terminal of the last battery. “TR”: relay signal terminal. If a high starting current is required by some electrical loads connected to the target battery (fridge, air conditioner, inverter etc), and the target battery cannot start them on its own and its voltage drops below 12.5V, the “TR”...
- Page 7 Switch 0°C charging Temperature Action < 0°C Stop charging > 3° C Resume charging Reduce charging - 20°C ~ 0°C current Resume normal > 3°C charging Battery selection The battery type for the target battery can be selected using DIP switches 2, 3 and 4. This setting will determine the charging parameters used for charging the target battery, such as charging voltage and temperature compensation.

- Page 9 No D+ signal, no charging Source battery voltage is < 11.0V. Slow flashing If the source battery voltage reduces (1 flash / 5 seconds) further to < 10.8V, the charging will stop. It Source Green resumes when the voltage returns to 12.5V. Fast flashing Source battery voltage >...
- Page 10 Equalisation: for selected battery types, the charger will perform equalisation charging by timer once a month with a higher charging voltage, in order to bring all battery cells to the same level. Equalisation charging will last for 2 hours. Please refer to the battery types table for more information.
- Page 11 If the internal temperature is > 85°C, the charging will stop. Charging will resume once the temperature drops to 60°C. If the internal temperature is > 75°C but < 85°C, the Overheating charging current will be reduced. Charging at full current (internal temperature) will resume once the temperature drops to 60°C.
