For vehicle-based charging in dual battery systems
The water-resistant DC–DC LiFePO4 charger is designed to safely charge a secondary LiFePO4 battery from a vehicle’s 12/24 V DC system. It can be especially useful in camper vans, boats, off-road vehicles, or other dual battery systems.
With its 10–36 V input range, the charger is available in LiFePO4-optimized 14.6 V / 29.2 V / 43.8 V output variants, depending on whether it is intended for a 12 V, 24 V, or 36 V battery system.
What is it for?
It is used to charge a LiFePO4 battery while driving or from an alternator in a secondary energy system using the vehicle-side DC network.
Why is it useful?
It can allow more stable and better-controlled LiFePO4 charging even when vehicle voltage fluctuates, especially in a dual battery system.
What environment is it for?
Thanks to its sealed, water-resistant construction, it can also be a good choice for vibration-prone, dusty, marine, or outdoor vehicle use.

Main advantages
- It charges directly from a DC source, meaning from the vehicle network to the secondary LiFePO4 battery.
- The LiFePO4-optimized charging voltages help provide a more suitable charging profile.
- The wide 10–36 V input range can support more stable operation even when vehicle voltage fluctuates.
- Its water-resistant construction makes it well suited for marine, dusty, or vibration-prone environments as well.
Installation – short guide
- Always choose the correct output voltage variant for the specific LiFePO4 battery.
- Install it in a stable, securely mounted, and preferably ventilated location.
- Cables must be sized for the current, and fuses on the positive line are recommended on both the source side and the battery side.
- Before connection, polarity and the battery BMS status should always be checked.
Warning
- It may only be used with LiFePO4 batteries, not with other battery chemistries.
- Charging a LiFePO4 battery below 0 °C is not recommended unless the system is specifically prepared for it.
- In vehicles with smart alternators, the use of a DC–DC charger can be especially beneficial.
- The exact charging current and IP rating depend on the model, so the specific version should always be selected for the intended application.
