Charge Your Deep Cycle Batteries Whilst Driving  - ePower DC2DC Chargers

When driving to new camp sites and adventures in your 4WD or motor home, it makes sense to use the extra power that your vehicle’s alternator is generating to charge your deep cycle battery bank (usually known as the “house battery bank”).

That’s where this 24V DC to 24V DC (battery to battery) charger can be used.

Once your vehicle’s alternator has charged your start battery, extra charge can be transferred from the start battery to your deep cycle battery bank, which means you should have more battery power when you arrive in your van or motorhome to set up camp.

Some 4WD guys who free camp simply use it to charge a deep cycle battery in the back of their 4WD, as it is ideal for topping the power up for an energy hungry esky style fridge box.

 It can also be used to top up a trailer boat’s electric motor batteries.

Note: There are two slightly different wiring methods depending on whether it is an in-vehicle installation or a towed vehicle installation. Note the two diagrams below are supplied to provide a general understanding only - always read the owner’s user manual before attempting installation or seek professional assistance.
