National Luna NLDC-25 DC-DC 25Amp Charger

The NLDC-25 from National Luna is an advanced DC-to-DC battery charger and isolator designed for dual-battery systems.

It efficiently charges an auxiliary or service battery from a vehicle's alternator or solar panel, with an output current of up to 25A.

Compatible with both traditional 12V and 24V vehicle alternators, as well as variable voltage alternators, the NLDC-25 ensures your battery is always charged and ready for your next adventure.

Its integrated MPPT solar controller optimizes solar energy with a maximum output power of 375W and supports solar panel voltages up to 42V.

Featuring a 6-stage charge algorithm, the NLDC-25 is suitable for all Lead-Acid battery types and automotive Lithium-Ion batteries, ensuring a safe and efficient charge. It includes three safety stages to detect damaged batteries and utilizes temperature compensation to optimize output voltage for safe and full battery charging under various conditions.

The NLDC-25 also supports the connection of a remote monitor, allowing users to track system and battery levels on a high-contrast LCD screen. With an IP67 (waterproof) rating, the NLDC-25 is built to withstand harsh environments and is protected against reverse-polarity, over-voltage, over-temperature, and over-current conditions.

30-Day Easy Returns

We get it. You've got a lot of choices when it comes to online retailers, so why should you even bother spending your hard-earned bucks shopping with us? 

Here are four short reasons why Open Road Overland is not like the rest of the bunch and why we believe that your shopping experience with us is not only 100% safe, but will also exceed your expectations, so you come back for more and maybe even bring your friends.

REASON #1: 100% SAFE & SECURE ONLINE SHOPPING

We use encrypted SSL security and are Level 1 PCI DSS compliant to ensure that your credit card information and every transaction on our website are 100% protected. 

REASON #2: DRIVING THE WORLD SINCE 1998

We started overlanding in 1998, way before overlanding was even a term. Since then we have spent the last 25 years zig-zagging the planet trail testing the types of equipment you find in our store. In other words, we learned the hard way what works and what doesn’t, through hands-on experience during our own adventures on 6 continents (yes, we still haven’t made it to Antarctica). To ensure that we add value to your adventure with the products you shop with us, our policy is that nothing goes on our website before it has been thoroughly reviewed. This means that you will not find anything in our store that we would not bring along our use on our own overland adventures.

REASON #3: WE HAVE DRIVEN ALMOST EVERYTHING

Secondly, we have been driving almost any type of vehicle you can think of over the years. This means that we have acquired a strong skill set to answer any question you have concerning your own vehicle setup, no matter whether you drive a standard passenger car, a pickup truck, or a fully rigged 4x4 overlanding vehicle. 

REASON #4: WE WANT EVERYBODY TO GO OVERLANDING

Thirdly, we strongly believe and promote that overlanding should be accessible to everybody, no matter what you drive, or what level of experience you have. That means that we can guide you as a novice overlander just starting out, as well as giving advice to you as an ultra pro with years of bushwhacking behind the wheel. That’s why you will also see both entry-level products, as well as top-of-the-line gear on our site, so we can cater to everybody looking to elevate their own overland adventures. No matter what, you can rest assured that the products you find in our store are here because they do the job they were made to do.
