12V Battery to Battery Charger - 12V / 30A

Sterling's new line of waterproof battery-to-battery (B2B) chargers can now offer all the programmability and flexibility of the BB Ultra line in a new waterproof package. It now incorporates a fan.

The external positioning of the fan (IP56 sealed) allows it to be safely destroyed in the event of total product immersion. In this situation, the product will continue to operate, but will not benefit from the advanced cooling. The fan can be replaced easily and inexpensively. In the event of a fan failure, the product will continue to operate, but its performance will be reduced to that of a non-fan cooled product.

This new model of battery charger allows a battery bank to be recharged much more quickly and completely from the alternator. It is easy to install and some models provide voltage conversions. This totally waterproof model has electronics embedded in the epoxy, which allows it to be IP67 waterproof. Its power is 400W.

The charging power will be maximum during 20 minutes then the power will be reduced to 18A to allow a good thermal dissipation (totally waterproof case).

More information about the battery charger.

The battery charger allows to quickly and completely recharge a service fleet from the alternator. Its assembly is simple and some models provide voltage conversions. The battery to battery charger is a product that has become increasingly popular in recent years, with Sterling's range, which is by far the most comprehensive on the market, expanding considerably to meet this growing demand. Like the alternator charger, it ensures optimal charging of service batteries from the alternator and is very easy to install.
Some models provide voltage conversion, so it is possible to recharge a 24 V battery such as the bow thruster from a 12 V alternator or recharge a 12 V service battery directly from a 24 V alternator.
Note also that the battery chargers allow to limit the current, this feature is useful to respect the charging constraints of the Lithium batteries or to limit the output power of the alternator and to preserve it from a premature wear.

You can also consult the product sheet which will give you an overview of our range of products dedicated to the optimization of the charging of service battery fleets.

The battery charger is connected in the same way as a relay. It allows the efficient charging of the connected battery bank from the alternator. The current entering the battery bank is limited by the nominal value of the device. This new model has the same characteristics as the previous improved range, and now has a special regenerative brake mode, an external fan and a model with a solar input. Its power increases from 300 W to 400 W. The battery charger starts at 13.2 V and stops at 13.0 V, so it does not discharge the input battery. With the "Ignition Feed" mode, special for regenerative brakes, the charger works down to 10.0 V.
