Sterling 12V 60 Amp or 120 Amp Waterproof Caravan Trailer Battery To Battery B2B Charger

Sterling Waterproof Caravan Trailer Battery To Battery Charger 60A 120A

What Is a Battery to Batter Charger?

DC Battery To Battery chargers allow you to charge a Caravan or Trailer leisure battery from your towing socket whilst driving.

Overview

The Sterling 60A or 120A Battery To Battery charger provides fast charging of your Caravan or trailer battery via your vehicle's towing socket.

It takes the low voltage at the towing socket and boosts it to provide the correct, multi stage charging profile for your leisure battery.

The 60A or 120A  Battery to Battery Charger is particularly suited to those who prefer touring, and so don't have frequent access to campsites with mains hook-up, and or those with vehicles whose engines are Euro 5/6 spec. With the 60A or 120A Battery to Battery Charger fitted you can be confident that your caravan battery will be charged at the end of your journey.

So why not a split charge relay instead?

The usual method of charging your Caravan Battery directly from the alternator via the towing socket, offers very poor performance because of the small cable and long run lengths used.

This results in large voltage drops meaning zero to little charging of the Caravan battery takes place and often the on-board fridge simply can't operate at the low voltage provided.

Electrical demands have increased in modern caravans (caravan movers etc.) meaning that good charging has become even more important, however, with the introduction of Euro 5/6 engine vehicles with 'smart' alternators, the charging performance has, in fact, become even worse.

This is because these alternators reduce their output voltage to save fuel when the starter battery is nearly full, which amplifies the already poor situation with voltage drop and effectively renders the charging system completely redundant, The Sterling Battery to Battery Chargers are a far more efficient option.
