## Overview

The Sterling ProCharge-B Battery to Battery Charger is a high-performance 4-stage charger that converts 12 volts input to a powerful 24 volts output at 30 amps. Ideal for charging auxiliary batteries in Mercedes Sprinter vans, it significantly reduces engine run time while providing versatile compatibility with various battery chemistries.

## Description

Why wait to arrive at your destination to plug in your battery charger? With the Sterling Power Battery to Battery Charger you can charge a 24V battery bank from another 12V input battery whenever the 12v alternator is running. Installation could not be simpler, simply plug the device between two batteries (e.g. starter and auxiliary). This on-board solution is able to provide a calculated 4 step charging profile to your batteries without being plugged into shore power. The Pro Batt C fools the alternator into working at maximum potential. The surplus power (power left over after charging the primary battery) is converted into a higher voltage and is used to charge your auxiliary battery bank faster (dependent on alternator, typically 5 times faster) than using just a standard alternator. As the Pro Batt C does not connect to the alternator there are no ECU nor warranty issues as there is no voltage rise on the engine management system.

## Features

- IF YOU HAVE A MERCEDES SPRINTER VAN YOU MAY WISH TO INSTEAD CONSIDER PART# bb1230 or bb1260 (for 12v to 12v applications) or bb122470 (for 12v input to 24v output applications in a Mercedes Sprinter) from Sterling Power Products.

- Ideal for charging auxiliary battery where relays alone don't provide fast enough charging for your daily demands
- Run your engine for 4 - 5 times shorter time to accomplish the same charging goals. - can be programmed for 4 battery chemistries.
