Digital Mobile Charge Overview :
The best way to charge a battery is using a 4 step battery charging curve, which cannot be
achieved from a standard alternator. Additionally a standard alternator cannot output a large
enough charge to power an auxiliary battery bank.
First and foremost, On Board Solutions’ Digital Mobile Charge ensures at all times that the power
required to run the primary system of the vehicle or boat engine is not affected. The engine start
battery is constantly monitored and receives top charging priority. The surplus power created by
fooling the alternator is amplified into a higher voltage by the Digital Mobile Charge and is used to
charge a secondary battery bank using a totally isolated digitally controlled 4 step charging curve.
The engine start battery cannot discharge through this system, even in the event of a unit failure.
In summary, the Digital Mobile Charge provides your extra battery system a charge that is
approximately 5 times faster than could be achieved in using the vehicles alternator. This provides
in-transit charging of extra battery banks and increases the life of the batteries by de-sulphating
them. The Digital Mobile Charge provides the same utility as an advanced regulator, a zero loss
battery isolator, and a 4 step battery charger.
Advantages of the Digital Mobile Charge:
1) Installation: Low Cost and Simple installation. Simply connect the unit to your start battery and
to your additional domestic battery bank.
2) No direct connections to the standard engine alternator, or to the outboard.
The Digital Mobile Charge replaces the need for a battery isolator and an advanced regulator, all
while providing in-transit charging.
3) The Digital Mobile Charge always ensures the engine start battery is maintained and top
charging priority.
4) Multiple Digital Mobile Charge units can be used. For example, if you have a 60 amp
alternator, and 3 battery banks (engine start, domestic bank, and bow thruster) then 2 units can be
used to run the domestic bank and the bow thruster bank. Internal programs will adjust their
charger patterns to accept the second unit, all while ensuring only excess power is used and the
primary start battery is not placed in jeopardy.
5) Ensures there is no voltage rise on the engine management system, eliminating the risk of
alarms or damage to the system.
6) The Digital Mobile Charge isolates both the engine start battery and domestic battery bank,
preventing any feedback through the unit.
