Product Description

    Details

    Charges a 24 volt battery from a 12 volt charging system. Capacity is 70A @ 12V input, and approximately 32A @ 24V output.

    Sterling's range of Battery to Battery Chargers (B2Bs) has grown significantly over the past few years in an effort to supplement the ever growing demand from the commercial vehicle, recreational vehicle, and marine industries. B2Bs have become extremely popular, as they charge batteries quickly to reduce run time, and without the need for complex wiring. You can provide the batteries with a fast 4-stage charging profile with a very simple and speedy installation; you get all the benefits of advanced charging without any of the drawbacks. Simply connect the B2B between the battery being charged and the battery you wish to charge.

    • Charges 24V auxiliary batteries from a standard 12V system
    • Each battery bank receives the correct charge current depending on its state of charge.
    • The voltage drop induced by a long cable run to a remote or bow-mounted battery is corrected for (these batteries tend to not be fully charged otherwise).
    • Alternator output is maximized, minimizing engine run time for battery charging.
    • Remote batteries are properly maintained and de-sulphated, extending battery life.
    • It is possible to charge batteries when voltages differ from the primary system.

    Sterling BB122470 battery to battery charger features:

    Multiple Activation Modes: Automatic for most non vehicle applications,
    Manual for remote activation.
    Regenerative braking (requiring ignition feed),
    Automatic regenerative braking, requiring no ignition feed.

    Step-up options: Output charging at 12V, 24V, 36V and 48V. Input voltages at 12V and 24V, depending on model. (This is 12V to 24V)

    Current is NOT taken from the input battery and given to the output battery. The B2B uses alternator power to charge the output battery. Manual mode and regenerative braking mode allows you to override this.

    Safety features:
    100% fire proof plastic box.
    No screws to corrode.
    Thermal power reduction.
    Multi stage fan cooling.

    Night Time Setting: Allows the unit to run at half the power, minimizing fan noise.

    Boost / Reduce Charging: The B2Bs ensure batteries get the correct charging profile irrespective of high or low input voltages.

    Auto on/off: Charger turns on at 13.3V and turns off at 13.0V (x 2 for 24V) and thus does not drain input battery. Regenerative braking mode allows the input voltage to drop to 12.2V (x 2 for 24V).

    Customizable Profile: Choose your own charging profile on the front panel.

    9 preset battery chemistry options: Including AGM, LiFePO4, Gel, Flooded and sealed lead acid.

    4 stage battery charging: The B2B charges batteries 5-20 times faster than a stand alone alternator.

    Very Simple to install: No Electronic Control Unit (ECU) issues. No complex wiring. No warranty issues. Fully prepared for smart alternators (regenerative braking).

    Remote control optional.
