Battery to Battery Chargers

Sterling Power B2B Chargers

Can charge a house battery bank off a starting battery having different voltage.

  • Fast and easy installation. Simply connect the unit to your starter battery and your aux battery.
  • No extra connections to the alternator and no extra wiring for a split charge system required.
  • Battery bank positive leads are insulated.
  • Engine starter battery is always well maintained.
  • Several battery-to-battery chargers can be used in parallel for higher output power or multiple battery banks.
  • No voltage rise on the alternator or the starter battery, thus no problems with the engine management system.
  • No warranty issues as the alternator and the main electrical system remains untouched.
