This DC to DC Charger is an excellent choice for anyone looking for a dual battery system that has all the features but without a hefty price tag. The system is designed to prioritize solar energy, reducing the load on your engine and ensuring efficient use of available power. Additionally, the automatic ignition detection feature isolates the starting battery when the engine is off, preventing unwanted discharge. The charger is fully automatic and easy to use, and the microprocessor-controlled circuit keeps your battery in optimal condition. It is capable of switching between six different charging modes: Qualification, Recondition, Bulk, Absorption, Check, and Maintenance. The heavy-duty Aluminium casing is durable and has a mounting bracket built in, along with a front panel with charge status LEDs and a push button to select between Lead acid, AGM, Calcium, GEL, or LiFePO4 batteries. It is also equipped with multiple safety protections, including overcharge, short circuit, over temperature, reverse polarity, thermal overload, and solar input overload. The charger is compatible with solar panels which have an open circuit voltage of 16 to 25V.

Handy Tip Multi State Charging Information

All-in-one chargers which have multiple charge settings to suitdifferent sized batteries and charging requirements. Capable of recharging the battery and maintaining the charge state indefinitely, they are particularly well suited to being continuously connected to a battery. Some models also have additional functions such as rapid boost charging and can also be used as a general purpose high current power supply. For further information see these types of possible charging states *may not be applicable to the unit you are viewing *
BATTERY TEST - Checks the battery to ensure it is ready for charging, polarity of leads etc.
DESULPHATION: Detects sulfated batteries. Pulsing current and voltage, removes sulfate from the lead plates of the battery restoring the battery.
SOFT START: Initial battery test to determine battery condition. Ift he battery is severely discharged, charger will begin the Soft Start stage. Charging starts with reduced current until battery voltage reaches a normal condition for charge.
BULK MODE: Major charging stage where the battery receives the majority of its charge. During this stage the battery is charged to up to 80% capacity.
ABSORPTION MODE: Completes the charge up to virtually 100% at a slower charge rate to protect the batteries working life.
RECONDITION MODE: Select “Recondition” mode, charges at higher voltage to recondition the sulfate of the battery to save battery life.
ANALYSIS: Tests if the battery can hold charge. Batteries that cannot hold charge may need to be replaced.
FLOAT: Low constant voltage, minimal charge current, battery is fully charged.
PULSE MODE: Maintaining the battery at 95-100% capacity. The charger monitors the battery voltage and gives
