Alternator to Battery Chargers up to 400A

$213.78$1,433.59

The Alternator to Battery charger (A2B) connects very simply to an existing alternator(s) and provides extremely fast and effective charge to the domestic/house bank (5+ times faster than a stand alone alternator). The A2B achieves this performance by pulling down the voltage on the alternator by putting a ‘load’ on it. This low voltage (at high current) is amplified to a 4 stage charging profile at the domestic bank. Due to the A2B’s internal splitting system there is the option to charge the starter battery too. The starter does not get advanced charging, it simply gets a sufficient maintenance charge.

Clear

Quick and Easy Installation. This charger is effective, simple and fast to install. It transforms the output of the alternator into a sophisticated multistage charger resulting in faster and more complete charging of your house / domestic battery bank.

Starter bank and domestic bank charger. This charger has an intelligent integral splitting system. The output is split to the starter bank and to the domestic / house bank. Domestic receives advanced charging.

Multiple alternator inputs. Numerous alternators can be fed to the input of the charger provided the total current rating does not exceed the charger’s rating. E.g. 400A charger can handle 4 x 100A alternators.

No alternator modification required. The charger is fitted between the alternator and battery(s) and, unlike conventional regulators, requires no modification or interference with the alternator whatsoever. This saves on time and bypasses any engine management systems (ECU) or warranty issues.

Over 5 times faster charging available output of the alternator and converts it to mimic that of a mains driven 4 stage battery charger. Consequently your batteries will charge faster resulting in less engine hours and a reduction in fuel used. This charger can therefore, pay for itself within a matter of weeks.

Largest model up to 400A (at 12V), 200A (at 24V).

Not suitable for any modern European vehicle or any vehicle equipped with an advanced ECU. For suitable products – look to the range of Regenerative Braking Friendly devices – the Battery to Battery Charger.
