Product Description


    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 fast charge batteries while you drive or cruise but without the need for complex wiring, touching your alternator, voiding the alternator's warranty, or tampering with the electronic control units (ECUs). You can provide the onboard 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 primary (usually the start battery) and the target battery.

    • 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 (model-dependent).

    Sterling BB1260 battery to battery charger features:

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

    Safety features:

    100% fire proof plastic box.
    Thermal power reduction.
    Multi stage fan cooling.

    Night Time Setting
    Allows the unit to run at half power so the fan noise is minimized.

    Boost / Reduce Charging
    The B2Bs ensure target battery gets 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), thus avoiding drain on the 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.
