Litime 12V 40A DC-DC Dual Input Battery Charger with MPPT for RVs, Campers, Trailers, Boats

When installing the DC-DC charger, there are a few precautions to be aware of. Firstly, it is recommended to install the charger vertically to enhance venting and heat dissipation. Additionally, positioning the DC-DC charger closer to the service battery is advised.

Can the battery be charged with both the solar and the alternator simultaneously? The DC-DC charger will automatically choose the DC input, rather than charging the service battery with both the solar and DC inputs.

Can the LiTime 12V 40A DC-DC charger activate the low voltage LiFePO4 battery? Yes, the LiTime 12V 40A DC-DC charger has a lithium battery activation function, but the battery needs to be disconnected from the load for activation.

Should breakers (fuses) be added when using a DC-DC charger? Yes, it is strongly advised. It is recommended to install a breaker between the DC-DC charger and the starter battery.

The key specifications of the LiTime 12V 40A DC-DC charger are as follows:

The LiTime 12V 40A DC-DC charger is compatible with multiple 12V battery types, including lithium, gel, AGM, and calcium. It can also activate dead lithium batteries in low voltage.

The charger is equipped with an ACC wire, a solar input terminal, a DC input terminal, and an output terminal to enhance the operational efficiency of the solar, alternator, starting battery, and service battery.

The charger features intelligent charging protection, including overvoltage input protection, output reverse connection protection, battery overvoltage protection, over-temperature protection, charging timeout protection, and BMS protection (for LFP battery).

The DC-DC charger is easy to operate, with simple instructions, LED indicators, and operation buttons. Users only need to choose the suitable battery type for their battery, and the charger will handle the rest.

The LiTime 12V 40A DC-DC charger also offers a reverse charging feature. When the starting battery voltage is between 3-12V and the living battery voltage is greater than 12.5V, press and hold "REVERSE CHARGE" for 3 seconds to start reverse charging.

The charger comes with a 2-year warranty and lifetime technical assistance. The aftersales team responds within 24 hours if you need any support from LiTime.
