    Dometic NDS Power Service DC-DC Charger 80A – 12V Battery to Battery Charger – PSB12-80

    The NDS Power Service PSB 12-80 DC-DC charger is a battery to battery charger. This means it’s a leisure battery charger that charges your leisure batteries from the alternator in your vehicle. Charge while you drive, arriving wherever your next adventure takes you with full batteries.

    12V battery to battery charger

    The NDS Power Service PSB 12-80 is for use in systems with a 12V leisure battery and a 12V starter battery.

    Optimised charging for all battery types

    NDS leisure battery chargers all incorporate Buck Booster and Opticharge technology, which stabilise charging, thus protecting battery health. The device allows you to select a charging regime depending on your battery type, whether lithium, AGM, gel, or flooded. The intelligent B2B charger then selects a specific charging curve that matches the specific state of your batteries, using an advanced analysis algorithm. Charging happens in 5 distinct stages, including desulphation and absorption, ensuring a perfect charge and extending battery life. These functionalities are simply absent from a more basic VSR charger.

    Easy to install in an existing battery charging system

    NDS leisure battery chargers are the only devices on the market which incorporate an AUX connection. This relay shifts all the charging load to the alternator when the engine is running, neatly bypassing existing connections and ensuring the leisure battery is charged directly at maximum performance.

    Which charger should you pick?
