DC to DC Converter 12-12V 20A/240W 40A/480W 60A/720W battery to battey charger for RV Marine EV
Self-regulated Charging Mode
The DC-DC battery charger will charge your house batteries from the starter battery to make sure it optimally and automatically charges to 100%. During the whole process, we use a 3-stage charging method (Bulk, Absorption, and Float) to protect the inverter and batteries.
Easy To Switch In Seconds And Prolong Battery Lifespan
Changing chargers is not a problem anymore. With just a simple turn of a switch, you can change among STD, Gel, AGM, and LFP batteries.
*A fully charged lithium battery will accelerate battery aging and affect battery life. Therefore, we adjust the charging voltage in LFP mode to 13.8V according to the charging and discharging characteristics of lithium batteries to effectively extend the battery life.
Intelligent Protection
DC-DC battery chargers isolate the input and output to prevent voltage transfer errors and interference with household battery charging. Equipped with multi-functional safety technologies such as over-voltage protection, over-temperature protection, and reverse polarity protection, it is safer to use.
Protect Your Batteries
This DC-DC battery charger is compatible with traditional and smart alternators. The D+ ignition wire can identify whether the generator is started, prevent the starting battery from being over-discharged, and protect the generator. The LC wire can automatically adjust the charging current to prevent excessive charging current from damaging the household battery. 18-16AGW or 22-20AWG copper cable is recommended.

FAQs
The DC to DC battery charger(link) is functional to charge batteries using the power of your generator or vehicle's alternator. When you are driving, you can use the charger to charge your off-grid battery (as secondary battery or house battery) with your operating battery (as primary battery or starter battery) connected to the generator/alternator. To put it short, you can charge both batteries while driving. That is why the charger is commonly installed between the generator/alternator and both starter battery & the house battery on the system. In a regular RV system, the generator/alternator ensures stable power supply to the starter battery, and the charger helps to use excess DC power from generator to supply the house battery through the starer battery.
Make sure it is a 12V battery system. The maximum charging current provided by the DC to DC battery charger does not exceed the current allowed by the house battery (as secondary battery).
LIAO 12V DC to DC charger works in supply voltage from 8V to 16V. The charger will charge battery during the range, while please be aware that the lower the supply voltage, the higher the amperage required to maintain the function.
Yes, there is a terminal on our charger to connect an ignition wire. It will have a steady output regardless of the fluctuations in the input voltage.
When you are driving, your RV alternator is charging your starter battery, and the alternator itself is also charging your house batteries along with the starter battery. To charge the house battery without connecting to the starer battery, you can install the charger then wire it into the starter battery. After the installation, you can place the third wire going to the ignition. By this method, it will work but only when the vehicle is running.
The selection of the A rating for a battery charger depends on the capacity of your battery and charging speed requirements. Generally, the output current of the charger should be around 10% to 20% of the battery capacity, so that the charger can fully charge the battery in an appropriate amount of time.
For example, if your battery capacity is 100Ah, it is best to choose a charger with a rating of around 10A. If you need a faster charging speed, you can choose a slightly larger charger, but do not choose a charger that is too large, as it may place an excessive burden on the battery and affect its lifespan.
