Sterling Power Pro Batt Ultra Battery to Battery Charger - Green Label

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 drawbacks.  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,
  • Output charging at 12V, 24V, 36V, and 48V.  Input voltages at 12V and 24V, Up to 800W rating.
  • 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: FIre Proof Box, Thermal Power Reduction
  • Night Time Setting: Allows the unit to run at half the power so the fan noise is kept down.
  • Boost / Reduce Charging: The B2Bs ensure batteries get the correct charging profile irrespective of high or low input voltages.
  • B2B turns on at 13.3V and turns off at 13.0V (x 2 for 24V).  Thus, does not drain 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 between 5-20 times faster than a stand-alone alternator.
  • Simple to install: No electronic Control Unit (ECU) issues.  No complex wiring.  No warranty issues.  Fully prepared for smart alternators (regenerative braking).
  • A remote control is optional.
