National Luna NLDC-40 DC-DC 40Amp Charger

The National Luna NLDC-40 is a DC-to-DC battery charger and isolator for dual-battery systems, capable of charging from a vehicle's alternator, solar panel or auxiliary DC source up to 40A output current.

It supports traditional and variable 12V and 24V vehicle alternators, and its integrated MPPT solar controller maximizes output power up to 600W, handling solar panel input voltages up to 42V.

The charger is compatible with all Lead-Acid and automotive Lithium-Ion batteries, thanks to its 6-stage charge algorithm.

In addition to the alternator and solar inputs, the NLDC-40 features a dynamic DC power input for voltages from 11V to 32V. Its advanced load-response algorithm allows it to support alternative DC sources with variable power levels (such as AC-DC power supplies, wind generators or DC generators). 

It automatically switches between input sources and includes three safety stages to detect damaged batteries.

Temperature compensation ensures safe and full charging under various conditions, and it also supports the connection of a remote monitor that can display system and battery information.

The NLDC-40 is built for harsh environments with an IP67 (waterproof) rating and protection 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.

  • Free Shipping to the lower 48 states, with no extra charges. Ever!
