DC2DC Battery Charger 40A /12V

The Enerdrive 40amp DC2DC Battery Charger with combined Solar Regulator is designed to accept multiple voltage inputs allowing you to charge your batteries through your vehicles alternator or your caravans solar panels. 

This means you can take advantage of the vehicles alternator whilst moving and your solar panels while you are stationary. 

The unit will automatically detect and select the best available input source for you.

Most other DC2DC chargers do not have this capability and a separate solar controller is needed. 

Multiple charging inputs allow you to accept voltage from your engine and solar panels and convert to 1  output to your battery bank.

Large battery cable connections  - DC M6 screw terminals 

Includes inbuilt (MPPT) solar regulator

Ability to charge Lithium, Lead Crystal, GEL, AGM, Wet Cell and also create custom profiles. 

Accepts 12 or 24v from your vehicle and a maximum solar input of 45V/800W

Thermo controlled fan cooling allows 40A output up to 40+°C 

Fully programmable LCD display to show which source is charging the battery along with charger status, voltage and amperage

Temperature sensor included in the charger for more accurate battery charging

During normal operation, the ePOWER DC2DC+ Battery Charger will do a full charge cycle to float stage on the house battery bank with ability to choose either GEL, AGM, Flooded, Custom Programmable or Lithium.

Once float stage is reached the charger transitions to a power supply mode to support any on-board DC loads.


Multistage Charging Process

The ePOWER DC2DC+ Battery Charger is a fully automatic, set and forget charger. It is designed to quickly and accurately recharge your deep cycle batteries utilising charger algorithms that help to maximise the life of your specialised deep cycle batteries.

The ePOWER DC2DC+ Battery Charger features multistage smart charging technology that enables the charger to be connected to your battery bank permanently. With the input of multiple sources, you can be assured of charging your batteries whenever underway; or when the sun is shining on your solar array.

As dictated by battery manufacturers recommendations, deep cycle batteries require a multistage charge sequence for perfect, fast and accurate charging. The Enerdrive ePOWER DC2DC+ smart charger delivers three primary charge stages.


Stage 1: Bulk or Boost charge; The battery is charged at full rated output current of the charger until the battery reaches its final charging voltage, known as its absorption voltage. In this step, around 80% of the battery is recovered as fast as possible.

Stage 2: Absorption Charge; With the charger voltage held steady, the remaining 20% is replaced with the charger allowing the current to taper off as the battery approaches full charge.

Stage 3: Float; Finally, in the float stage the charger voltage is lowered and held at a constant and safe predetermined level. This prevents the battery from being overcharged, yet allows the charger to supply enough current to make up for the self-discharge losses of the battery, while supporting any additional loads connected to the battery (such as DC lighting and refrigerators). This stage allows for the charger to be used as a DC power supply.


Smart Charging Feature

The ePOWER DC2DC+ Battery Charger will regulate its output based on the loads connected to your battery bank.

This function is important to maintain the life of your battery bank as some battery chargers mistake loads for discharge and continue to keep the batteries in the bulk or absorption stage for extended periods of time, which will damage the battery bank.

The ePOWER DC2DC+ Battery Charger has two methods of load-based regulation to ensure your battery charger transitions to float when it should do so.

Battery Temperature Sensor included standard with all ePOWER Battery Chargers.
