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.


Features – Smallest model 80A – 130A (at 12V).

  • Battery and alternator temperature sensing. The chargers disengage the unit in the event of the alternator temperature getting too high, it then re-engages the unit when the alternator cools down. The same thing happens when the batteries get too hot.
  • Multiple charging profiles. Chargers have AGM, Gel, Flooded lead acid, sealed lead acid and calcium charging profiles.
