Sterling’s range of Battery to Battery Chargers (B2Bs) has grown significantly over the past few years. This is in an effort to supplement the ever growing demand from the commercial vehicle, recreational vehicle and marine industries. The B2Bs have become extremely popular as they fast charge batteries as you cruise along without the need for complex wiring, touching your alternator, voiding the alternator’s warranty and 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. All of the benefits of advanced charging without any of the draw backs. Simply connect the B2B between the battery being charged and the battery you wish to charge.
Multiple activation modes:
Automatic for most non vehicle applications.
Manual for remote activation.
Regenerative braking (requiring ignition feed). Finally, Automatic regenerative braking requiring no ignition feed.
Very simple to install. No Electronic Control Unit (ECU) issues. No complex wiring. No Warranty issues. Fully prepared for smart alternators (Regenerative braking).
4 stage battery charging. The B2B charges batteries between 5-20 times faster than a stand alone alternator.
9 preset battery chemistry options including AGM, LiFePO4, Gel, flooded and sealed lead acid.
Customizable profile – choose your your own charging profile on the front panel.
B2B turns on at 13.3V and turns off at 13.0V (x2 for 24V). Thus, does not drain input battery. Regenerative braking mode shall allow the input voltage to drop to 12.2V (x2 for 24V).
Boost / Reduce Charging. The B2Bs ensure batteries get the correct charging profile irrespective of high or low input voltages.
Night time setting allows the unit to run at ½ power so the fan noise is kept down.
- 100% fire proof plastic box
- no screws to corrode
- thermal power reduction
- multi stage fan cooling
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.
Output charging at 12V, 24V, 36V and 48V. Input voltages at 12V and 24V. Up to 800W rating.
