Battery to Battery Charger 12V – 12V 120A

Waterproof ( built to ) IP66 models. These units have the benefit of being epoxy potted so that the charger is sealed off from water and dirt ingress. The cooling fan is not sealed and is rated at IP55, the fan is designed to be easily replaced in the event of major immersion .

This has both an auto setting and an ignition setting.  If you have a regenerative system simply select the ignition setting and even when the vehicles electrics drop top 12.6 volts (or lower) we simply take that voltage and boost it up into your aux battery system ensuring steady power charging regardless of the vehicles voltage variations. Fully adjustable for battery type and other functions.
Encapsulated electronics, fully waterproof thermostatically controlled fan cooled for smaller footprint. Fan is not IP68, however, it is designed to be easily replaced in the event of a failure.
Other major advantages of this product;
Voltage Reduction, SOME MODERN ALTERNATORS COME PRE SET WITH A VERY HIGH STANDARD VOLTAGE IE ABOUT 14.8 – 15 VOLTS, this voltage is fatal to some battery types. Up until now, most Sterling Power products have been all about increasing voltage to boost charge the batteries, however some alternators now come standard with very high output voltages, on the surface this may seem like a good idea but the voltages on some alternators are way above the recommended voltages for the likes of AHM, GEL, and Lithium batteries. Voltages of 14.8-15V are not uncommon, in this case the voltage must actually be reduced not increased, this model has the ability to boost or drop the alternator voltages depending on the battery type selection and the battery charging requirements, ie you can feed 15 volts into this or 13.8V and you will still get 14.4 (IF THAT IS YOUR SELECTED / REQUIRED SETTING) .
