Description

In dual battery setup, a DC DC charger allows you to charge an auxiliary battery from the alternator whilst driving. With the DC DC charger, the main battery remains unaffected and always ready to start the car. And the DC DC charger can activate lower input voltage operation to suit vehicles with smart alternators. This 12V DC DC battery charger can utilize a solar panel or a starting battery linked to the alternator, while giving the priority to a solar input to place less load on the alternator. The DC to DC charger is suitable for LiFePO4 and lead acid: AGM, gel & calcium batteries, and allows you to re-select the battery during charging. With the memory function of this battery to battery charger, you don’t need to re-select the same battery type every time. And 6-stage charging is engineered for better maintenance & longer lifespan of battery. If you’re planning an off-grid camping, this 20A DC DC battery charger will be your perfect companion for a dual battery setup.

A very happy customer.

"I had this mounted in the car and it works brilliantly. It keeps on charging after the car is turned off but only until the battery hits about 11. 8V. Then it shuts down and won’t restart until the car is running again. I’m really happy after a couple of months."

DC Charger

"Product is good and as described. Aramex in Australia is pretty hopeless. They did deliver to a commercial address this time but they are always very slow and the tracking information is not accurate. Arrived three days after being advised "Coming today""

Q&A

I have the dc to dc charger connected according to instructions. When I start the vehicle, it doesn’t charge. If I press and hold the selection button, the charging light will blink a few times and then stop. What am I doing wrong?
Please disconnect the charger from everything then put them back on to reset the unit.
Why is my dcdc charger have the power light on and charging light on and the lithium battery picked on then all flashing then lights go out and start all over again
That might happen when the engine isn't running and the charger is drawing power from the the main battery until its voltage drops under 12.5V.
Does this unit prevent drain of starting battery?
Yes, it stops drawing power at 12.4V.
