Warranty Information

Accessories 1-year material warranty

1. What is a DC-DC charger? What is its purpose?

The DC-DC battery charger is installed between the starter battery and the house battery. For the RV system, The generator ensures stable power supply to the starter battery, and uses the extra power of the starter battery to supply power to the house battery.

2. How to choose a suitable battery charger?


1. Make sure that the entire system is a 12V system

2. Ensure that the maximum charging current provided by the DC-DC battery charger does not exceed the maximum charging current allowed by the house battery

3. How to set the charging voltage value of the charger?

The DC-DC battery charger adopts the design of the DIP switch and it provides 6 charging voltage settings through five gears. These six charging voltages meet the requirements of lithium batteries and lead-acid batteries in order to provide more charging options. SW5 switch is the selection switch for switching between lead-acid batteries and lithium batteries.

4. What is the D+ Ignition cable? Is it necessary to connect?


The D+ Ignition cable is a design method used to identify whether the generator is started. This design method can well prevent the starting battery from being over-discharged during the charging process. When the generator is started, a signal will be obtained on the D+ Ignition cable, which will light up the indicator light of the charger.

The DC-DC will not power on or operate until the D+ ignition cable is connected.

5. How can I get these cables?

The battery temperature sensor for DC-to-DC car battery chargers can be purchased at the Renogy store. The D+ ignition cable can be purchased at the local store or online, it suits both D+ and LC terminals. 18-16AWG copper cable recommended.

    60 amp DC to DC Charger

    Posted by Mike L on Nov 16th 2022

    Added 60 amp DC to DC charger to my truck and trailer setup to take advantage of my truck charging system. Works great to charge my Lithium batteries while traveling on cloudy days when solar is not available and at night. Produces full 60 amps even when my F150 truck is just idling.

    Dependable and Inexpensive Battery Charging

    Posted by TWH on Nov 14th 2021

    Simple installation, except running cable from truck battery to truck bed. Started my truck, saw 40 amp charge via Victron 712 battery monitor. 30 minutes later the batteries were charged. More dependable than solar and far less expensive. If you don’t boondock much but travel a lot, this is an inexpensive alternative for charging your batteries.

    DC/DC charger that does what I need it to do......

    Posted by dressageman on Oct 12th 2021

    I bought this in May 2021 to charge my 240 AH LiFePO4 trailer battery when on the road traveling. I installed a Renogy 2000W PSW inverter in the trailer at the same time with the intention of running my refrigerator on 120v while on the road. This is much safer than using the refrigerator on propane, especially when coming in to a fuel stop with the open propane flame in proximity to potential fumes at the gas pumps. The unit installed easily and works perfectly. My refrigerator uses 25 amps of power and this unit easily keeps my battery fully charged while on the road. It works seamlessly with the 400W of solar I have on my trailer roof. The charger adjusts to the needs of the battery and protects my expensive lithium battery bank from over and under charge. You can easily set it up for any type of house battery from flooded lead acid to LiFePO4. The unit is well built but I am critical of the very small terminals. Size 1 terminal lugs do not fit on the terminal blocks without some minor modification. That is unacceptable because the larger cable is needed due to the long runs between the vehicle battery and the DC/DC charger mounted near the house battery in the trailer. Other than that shortcoming, the unit has performed perfectly over about 6000 miles of travel this year. My house battery is always in tip-top shape, even when traveling at night when solar is unavailable. Use an Anderson connector between the vehicle and the trailer and you'll have the perfect setup. Buy the correct size cable and good quality, ,correctly sized fuses to avoid tripping issues. I initially bought circuit breakers and ended up replacing them with fuses after having tripping issues. Fuses work perfectly and I have not tripped a circuit once since I installed them. Follow Renogy recommendations on cable and fuse sizing and you'll be fine.. You'll always arrive at your campsite fully charged and ready to enjoy the day or night if you use this DC/DC charger. Buy with confidence.
