RV’s and special vehicles : How to select the correct DC/DC Booster ?
Whether designing a camper or an emergency vehicle, the battery is one of the most critical components of a vehicle. In addition, as vehicles carry more and more electrical devices, they require more power to operate them. Auxiliary batteries are installed to power these additional equipments. The best way to take care of your batteries is to ensure proper charging levels with the appropriate charge cycles and current level. The use of DC/DC chargers is one of the recommended ways to achieve this. In this article, we propose you to discover the essential criteria to choose your DC/DC battery chargers for your RV’s or special vehicles.
What is a DC/DC battery charger ?
Especially important for multiple battery installations, DC/DC chargers ensure that your auxiliary batteries are charged and isolated from each other. This gives you extra power resource and reliable performance when you need it. A DC/DC charger (also known as a battery to battery charger, DC/DC Booster) always keeps your second battery at 100% charge, even when vehicle if fitted with Euro5/6 smart alternator.
And because it's DC power, the DC/DC charger doesn't rely on fluctuations in current from the alternator, so you get more clean power and less strain on your car's electrical system.

How to select the proper DC/DC battery charger ?
Here are some tips to help you choose the best DC/DC charger for your vehicle.
A DC/DC charger able to charge different type of battery technology
Many types of batteries are now available on the market. These include traditional lead-acid and calcium batteries, as well as the more expensive and sophisticated AGM and lithium batteries that act as auxiliary power.
The best DC/DC battery chargers on the market provides several battery charging profile. Up to four battery profiles could be available to fit the appropriate charging characteristics. This is because, depending on its type, a battery will have different charging requirements and could be damaged if it receives inappropriate charging state of charge and voltage.
A DC/DC charger able to accept several power source
Another factor you should consider is whether the DC/DC charger can accept different power inputs. As a reminder, the engine's alternator is the primary power source for a vehicle. Based on engine RPM and built-in regulation It will provide the proper voltage and current to the battery. Please note that with new environmental regulation the output power from smart alternators are less efficient.
Some vehicle manufacturer now carry their own auxiliary power sources, such as solar panels. Fitting your solar panels with you is becoming increasingly useful, especially when driving in remote areas. Users can then charge their batteries while they are resting. The ideal DC/DC charger must therefore be able to accept this auxiliary power with a built-in MPPT regulator.
An DC/DC charger with the adequate amperage output
Based on time the owner will drive the DC/DC battery charger should provide enough power to fully charge the auxiliary battery. Large unit will provide up to 60 amp while driving. Make sure your DC/DC charger will fully charge your battery within 8/10 hours maximum. Some units provide a unique double output. In this case 100% of power will charge the auxiliary battery.
A DC/DC charger able to provide full power in hot environments
Check the operating temperature limits of the DC/DC charger. If you use a booster , another important consideration is the temperature limit of the device. Some drivers operate their vehicles in extreme weather conditions. Hot conditions in the engine compartment and anywhere else you install the charger can damage poor quality DC/DC chargers. In addition, some products will have an efficiency that collapses with a rise in temperature.
A DC/DC charger with easy access panel information
A battery charging system should have the proper indicators and display, which will give you an idea of its current status. Here are some important information that you should be able to see on the charger:
- The type of battery being charged
- The current charge level
- Error status
You should pay particular attention to the fault status at all times, giving you enough time to react if necessary. As part of its long-term reliability, you need a charger with a good warranty for peace of mind. High-quality manufacturers offer longer warranty period, which shows their great confidence in their products. Some units provides Bluetooth in order to check all parameters from a dedicated smartphone app.
