Sterling Power Battery to Battery Charger

Sterling Power's Battery to Battery Chargers are a smart charger that charge batteries quickly while avoiding wiring, your alternator, and electronic control units (ECUs). These chargers provide a 4 stage charging profile with a quick and easy installation. The Battery to Battery Chargers only give benefits of charging without any downsides. It's as easy as connecting it between the battery being charged and the battery needed to be charged..

  1. Multiple Activation Modes: Automatic for most non vehicle applications, Manual for remote activation. Regenerative breaking (requiring ignition feed), Automatic regenerative breaking requiring no ignition feed.
  2. Output Charging12V, 24V, 36V, and 48V, Up to 800W rating.
  3. Much Larger Model Up To 3000W Coming Soon
  4. Current Is NOT Taken From The Input Battery And given to the output battery, the B2Buses alternator power to charge the output battery. Manual mode and regenerative breaking mode allows you to override this. 
  5. Safety Features:  100% Fire proof plastic box, No screws to corrode, Thermal power reduction , Multi stage fan cooling
  6. Night Time Setting: Allows the unit to run at half the power so the fan noise is kept down.
  7. Boost / Reduce Charging: The B2Bs ensure batteries get the correct charging profile irrespective of high or low input voltages.
  8. B2B turns on at 13.3V and turns off at 13.0V (x 2 for 24V). This does not drain the input battery. Regenerative breaking mode allows the input voltage to drop to 12.2V (x 2 for 24V).
  9. Customizable Profile: Choose your own charging profile on the front panel.
  10. 9 Preset Battery Chemistry Options: Including AGM, LiFePO4, Gel, Flooded and sealed lead acid.
  11. 4 Stage Battery Charging: The B2B charges batteries between 5-20 times faster than a stand alone alternator. 
  12. Very Simple To Install: No electronic control unit (ECU) issues. No complex wiring. No warranty issues. Fully prepared for smart alternators (Regenerative Breaking) Remote Control Optional.
