25A 12V T0 24V Advanced Dc-Dc Charger

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), that 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. For Lithium batteries, the temperature sensor unlocks a charging protection to be selected to prevent charging when below 0°C which could damage the battery.

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: via 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.

This charger features optional terminals that enable greater precision in voltage measurement of the target battery by bypassing the voltage drops in heavy-duty charging cables.

The charger includes 4 LED indicators to display the battery charging stage and diagnostic information.
