Bluetooth® monitoring app

Connect to the app for real time updates. Get an accurate Volt and Amp reading on what you’re generating via your solar setup and DC-DC input at the press of a button. On top of that, the app will monitor how your battery is doing too, making sure you can stay completely across your setup. The app also keeps a record of previous charge cycles and will also give you status ‘warnings’ when something’s not quite working in your setup.

Charge your battery while you drive or with the sun

Juggling your 12V setup so that the beers stay icy cold, and the lights will come on at night can sometimes get pretty complicated. Our 25A DC-DC Charger with MPPT Solar Regulator takes the confusion out of your battery setup. Perfect for everyone from weekenders to off-grid tourers, our charger is ideal in setups using Lithium, AGM/Gel, Lead Acid or Calcium Batteries.

Our DC-DC Chargers will charge your batteries at up to 25A for every hour you drive. Compatible in vehicles using either a traditional or fixed/smart alternator, our DC-DC will charge your batteries using a five-stage charging algorithm, overall prolonging the life of your auxiliary batteries.

The second output on the charger is our inbuilt 25A Maximum Power Point Tracking (MPPT) regulator designed to generate power up to 15% quicker than traditional Pulse Width Modulation (PWM) regulators. Equipped with our five-stage charging algorithm, the regulator will quickly and, more importantly, safely, bring your batteries back up to full charge.

Its compact construction means that the unit will fit most smaller setups including inside some battery boxes or tight 4x4 canopies.

Our DC-DC is compatible with the “Hardkorr DC-DC Charger” app, available on the Google Play and App Store. At the press of a button, the app will give you access to a live feed on your batteries, solar and DC input.

Purchased recently to set up as a portable DCDC & Solar charger unit for a battery box & caravan solar blanket controller. Very compact & can be mounted on a flat base, plus Bluetooth monitoring was an important feature. There is no user profile & remember to enter the Ah of the Auxiliary battery under Settings (menu bars top left of screen) in the App.

Working for solar, but yet to recharge the battery box in the Ute with a DCDC start battery connection.

To connect the phone with Bluetooth to the charger using the Hardkorr App first connect an auxiliary battery & hold the green background POWER button down for 3 seconds until a battery type LED indicator blinks (Page 5).
Now the appropriate battery type can be selected (press to cycle through the options) AND the Bluetooth pairing mode is active.

Start the App, a white battery icon & 'searching' notice is seen, this will very quickly show a 'Connect' link to touch / select.
Exit the setup mode by a 3 second long press.

Bought this charger from BCF. Had it fitted correctly but was faulty. The app kept indicating high voltage. Disconnect the solar. No solar fitted. Contacted Hard Korr. Only response was sorry you have had a problem with our product. Contacted them again. No response.

Took the charger to BCF and after some discussion they replaced it. This charger appears to be working ok.

Very disappointed with Hard Korr. I will never buy from a company that cannot be contacted by phone. Why don’t you supply a phone number or at least call the customer back when request.
