- Page 2 Overview This powerful 90A 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. 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 Reference Description Source battery positive input (+) Common negative (-) Target battery positive output (+) Green terminals Remote meter port DIP switches LED display Bluetooth dongle port Cooling fans Installation Install the battery charger as close to the target (OUT) battery as possible and keep the surrounding area clean, tidy, and well ventilated.
- Page 4 Note: DIP switch 2 sets the trigger method to start the charger: • If the trigger is set to D+ signal, the charger will require a D+ signal to operate. If there is no signal applied to the D+ terminal, the charger will not turn on. •...
- Page 5 temperatures vary substantially from the baseline temperature of 25°C. The sensor performs two main functions: • Charging voltage adjustment. The charging voltage for the target battery is compensated up or down depending on the ambient temperature to regulate the speed of chemical reaction inside the battery. The voltage will increase in the winter and decrease in the summer at the rate of 18mV for each degree Celsius away from the reference temperature 25°C.
- Page 6 • And the source battery (IN) is the vehicle’s starter battery • And DIP switch 2 of the charger is set to “D+” signal (please refer to the DIP switches section for more information). In such case, the charger will only operate at times when the alternator sends a “D+” signal to this “D+”...

DIP switch 2: select the trigger method to start charging. DIP switch position Description Voltage control mode: there is no need to connect “D+”...
- Page 8 DIP switches 4, 5, and 6: battery selection. The battery type for the target battery can be selected using DIP switches 4, 5 and 6. This setting will determine the charging parameters used for charging the target battery, such as charging voltage and temperature compensation.
- Page 9 Note: the battery type should not be changed whilst the charger is powered. If the battery type needs to be changed, first power off the charger, then change the DIP switch configuration, then turn the charger on again. Note: any lithium battery used with this charger must have a Battery Management System (BMS).
