Discover LiTime high-performance DC to DC battery chargers—each dc to dc lithium battery charger delivers efficient, vehicle-powered charging for RVs, boats, and off-grid systems to protect battery health and extend lifespan.
A DC to DC charger converts and regulates power from a vehicle’s alternator to safely charge a secondary battery, ensuring optimal charging for lithium and other battery types.
The LiTime DC-DC battery chargers are compatible with both conventional and smart alternators. However, since conventional alternators provide a steady voltage during charging and smart alternators adjust their output based on operating conditions, it is essential to connect the charger to the smart alternator using the included Signal cable through the Vehicle Ignition Port.
Yes, our DC-DC lithium battery charger is engineered for versatility and performance. It not only works seamlessly with a wide range of batteries but also includes powerful features to maximize their potential.
Yes, the LiTime DC-DC charger for lithium batteries are equipped with a full suite of high-quality safety measures. It actively protects against over-voltage, low-voltage, over-temperature, short circuits, and reverse polarity to ensure safe, reliable operation.
Additionally, its advanced design isolates the input from the output, which prevents voltage transfer errors and protects sensitive electronics from interference during charging.
The DC to DC lithium charger includes LED indicators to show the charging status.
If your DC-DC charger isn't charging your LiFePO4 battery, even with normal or flashing lights, the issue is often related to wiring, settings, or vehicle voltage.
We've created a detailed troubleshooting guide to help you diagnose and fix the problem. You can find it here: DC-DC Charger Troubleshooting Guide
A DC-DC battery charger converts DC voltage from one battery bank to another. It’s ideal for charging a 12V battery from a vehicle’s electrical system, whereas an AC charger requires an external AC power source (like a wall outlet).
A properly installed dc to dc battery charger typically won’t drain the main (starter) battery.
A quality dc to dc charger for lithium batteries only runs when input voltage is above a safe threshold (or when ignition/engine is on) and stops charging if starter-battery voltage drops too low, helping prevent overnight drain.
