12v 30amp Compact DC to DC Battery to Battery Charger for lead-acid and lithium batteries

Photonic Universe 12v 30A compact DC-DC Battery Charger is fully automatic and ideal for leisure vehicles, commercial and special purpose vehicles, boats, and any other systems with multiple 12V 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. The product is compact, lightweight and features high frequency switching and buck-boost power conversion technology for reliable, consistent performance.

Key Features:

Fully-automatic, high-frequency, multi-stage charging: ensures the battery is charged safely and quickly. Pulsed charging keeps temperatures low and evens electrolyte consistency to ensure a long battery life.

Easy battery type selection: with the use of dip switches, the unit can be switched between Lead Acid, AGM, Gel, LiFePO4, or Lithium-ion battery types.

Safe unattended charging: the unit features inbuilt safety functions (protection against overload, overheating, overvoltage, over-discharge, short circuit, and reverse discharge of the battery), which allow the charger to be left permanently connected to the batteries for unattended automatic charging.

Advanced temperature protection and compensation: When paired with an optional external temperature sensor (sold separately), the charger provides advanced temperature protection for Lead Acid batteries. The battery will be charged at varying voltages to compensate for voltage loss during temperature changes.

Data monitoring: the charger includes ports for a remote meter or a Bluetooth module (both sold separately), allowing data to be viewed on an LCD display or through a mobile phone app when connected.

Continued charging during battery/load use: the charger will continue to operate at full power whilst energy is drawn from the battery during use. The unit will maintain the charge if the battery is already at full capacity. Any 12V loads may also be left permanently connected and running whilst the DC-to-DC charger is in operation, and will be protected against overvoltage and voltage fluctuations.

Ignition on/off control: by connection to the ignition control through the D+ terminal, this charger can be set to begin battery-to-battery charging immediately when vehicle ignition is turned on and stop charging when the vehicle is turned off.

Wake-up function for Lithium batteries: When the Battery Management System (BMS) of a lithium battery goes into the protection mode, the charger can automatically activate the BMS and continue charging the lithium battery.
 

Additional Features:

This charger utilises adaptive charging routines that will measure the voltage of the source battery throughout the charging process and gradually adjust the charging current to prevent over-discharging the source battery. As the source battery recovers the charging current will also gradually increase as well. If the voltage of the source battery drops too low then the charging current will be stopped until the source battery has reached the recovery voltage.

The charger includes 4 LED indicators to display the battery charging stage and troubleshooting for faults.

Compatibility:

This DC-to-DC battery charger is suitable for use with 12V lead acid, AGM, Gel, LiFePO4 and Lithium-ion (NCM) batteries. It is not compatible with 24V batteries or a combination of 12V and 24V batteries.
