Features: Charge your batteries over 5 times faster. Input an extra 50% extra power into them plus de-sulphate the batteries. Make them last longer. Can be used with 2 alternators. This new product incorporates a split charger diode system to charge 2 battery banks. However, on the domestic battery bank only, there is a unique power amplifier on this channel. This ensures the alternator works at its maximum output (it could also be used on a single output battery charger or other current limited power source) and increases the voltage of the domestic line (with software digital control) up to 14.1 volts for AGM, 14.4. for gel and 14.8 for open lead acid/traction. Using the same advanced program in the very successful Digital Advanced Regulators. This product could be used on any other product which has current limit on it. For example, if you have an old fashioned constant voltage transformer based battery charger (or a constant current with low preset voltage controls and poor trimmer performance) which does not work very well, then simply attach this to the output of the old battery charger and you will have the latest digital controlled 4 step charger, with all the programs, remote control and split output of the latest chargers on the market. Plus, at least a performance increase of about 500%.
