DCDC Chargers

What battery types does an iTechworld DCDC charger support?

An iTechworld DCDC charger supports lead-acid, AGM/gel, lithium and calcium battery types.

Does an iTechworld DCDC charger have a solar input?

Yes! An iTechworld DCDC charger will have an inbuilt MPPT controller which has been optimised to be approximately 30% more efficient with your solar panel than conventional controllers.

Is an iTechworld DCDC charger waterproof?

Yes! Our 25amp and 40amp chargers have an IP67 rating against water and dust intrusion. Our 60amp DCDC Charger is not waterproof.

Can I mount an iTechworld DCDC charger under the bonnet?

Yes! Thanks to its rugged, heavy-duty design and IP67 waterproof rating, our DCDC25 and DCDC40 chargers can be mounted virtually anywhere. Our DCDC60 charger cannot be mounted under bonnet.

Can I use my existing Anderson plugs with an iTechworld DCDC charger?

Yes, an iTechworld DCDC charger will plug into your existing Anderson plugs. Please ensure the cabling used is suitable for your DCDC charger.

I would rather keep my solar setup separate, will that be an issue?

No, the solar side of the DCDC charger is optional. You do not have to use it.

Can I use a non-iTechworld solar panel with an iTechworld DCDC charger?

We always recommend an iTechworld solar panel and an iTechworld DCDC charger to ensure the system's optimum performance. However, you can use non-iTechworld solar panels, provided their specifications match the charging parameters of the DCDC charger

My DCDC charger is not lighting up or turning on

Please ensure your cranking battery is above 13.2V when your vehicle is up and running (over 12V if your vehicle has a smart alternator with the ignition cable connected), and your charger should light up. Failing that, follow the instructions below:

My DCDC charger is lighting up but not outputting power from the alternator

The DCDC charger will not start if your battery is full or very close to full. To get it to start outputting power, please ensure your auxiliary battery is drained to at least 85% (13.1V for lithium batteries). The charger will not kick in if no powe

My DCDC charger is lighting up but not outputting power from my solar panel

The DCDC charger will not start if your battery is full or very close to being full. To get it to start outputting power, ensure your auxiliary battery is drained to at least 90% (13.1V for lithium batteries). The charger will not kick in if no power

I'm not getting the expected amperage from the DCDC charger

The DCDC charger will not kick in if your battery is full or very close to full. To get your charger to increase its output, ensure your auxiliary battery has been drained to at least 85 - 90%. Please remember that the closer the battery gets to bein

My DCDC charger is discharging my cranking/starting battery too far

The ignition cable may be connected to a source not controlled by the ignition. This may give your charger a false reading and cause it to drain your cranking battery too low. The easiest way to test this is to completely disconnect your DCDC charger

My DCDC charger is interfering with my vehicle's radio

Relocate the DCDC charger and install it as far away from the car's radio antenna as possible. Use a ground loop isolator to split the DCDC charger's 'ground' from your radio's 'ground'. Ground the DCDC charger at a different point or directly to the

My DCDC charger is making a 'clicking' sound

An iTechworld DCDC charger may 'click' for two different reasons. Solar input:. The solar voltage/current is not great enough to engage the charging algorithm (16V and 3A), but it exceeds the specifications of the DCDC charger (25V). Vehicle input:.

I can't change the battery charging profile on my DCDC charger

Click and hold the MODE button for 1.5 seconds and let go. You should see the flashing LED move across the profile options. Continue doing this until you have reached your desired battery profile.

My solar panel does not appear to engage the DCDC charger

All iTechworld DCDC chargers prioritise vehicle input over solar. Even when the vehicle has stopped, the DCDC charger will charge the auxiliary battery via the cranking battery to reach a voltage of 12.8V. This is to get the highest amount of current

My DCDC charger is powering up, but not charging

This could be due to several factors, as follows:. - The DCDC charger must have over 12.8V input from the starting battery. - The auxiliary battery must be below 13.1V for 40A and 20A chargers. If you have an older 25A charger, it must be under 12.4V

I am not getting the expected amperage from my DCDC charger

Please go through the following troubleshooting steps:. 1. Check the voltage on the cranking battery. 2. Check the voltage on the red Anderson plug connected to the DCDC charger. The voltages should be the same. 3. If the voltages are different, the

My DCDC charger is discharging my cranking/starting battery too much

If the ignition override cable is connected to a source not controlled by the ignition, the charger may display a false reading and thus allows your charger to draining the cranking battery too low. The easiest way to test is to completely disconnect
