DC-DC Chargers

Overcome the long cable voltage drop and properly charge your trailer or caravan battery with a DC-DC charger.

Balancing efficiency and performance a DC-DC charger is designed to deliver a controlled three-stage charge to your secondary battery, protecting the starter battery from excessive discharge and ensuring long term health of both batteries.

Todays advanced smart alternators, which are primarily designed for optimal efficiency and reduced emissions deliver variable output and voltage and shut down when not needed. The DC-DC charger can be placed between the alternator or starter battery and service battery and by employing controlled charging, will maintain a charge to the secondary battery without overloading the alternator. Additionally, this will isolate the starter battery when the engine is not running to ensure the starter battery is not depleted.

While DC-DC charging requires more set up versus charging directly from your alternator, the DC-DC charger will ensure you get a 100% charge and maintain your expensive batteries in peak health. Rarely does an alternator run over 14V and with most batteries requiring at least 15V to reach 100% charge and keep the battery in good condition, DC-DC charging is vital.

There are several different DC-DC chargers available that provide a variety of solutions for various applications. Batteries are expensive so choosing a quality DC-DC charger will not only protect your investment but will give you peace on mind and confidence in your system.
