  • BB484830 – 48V to 48V DC DC charger ~1600W. 30A. ideal for charging between 2 sets of 48V batteries. Lithium or lead acid.
  • This charger correctly calculates the battery’s or bank of batteries’ charging needs and boost charges with the right charging algorithm for your battery anytime the boat or vehicles alternator is running. It also goes into lower float voltage when the battery is full. Doesn’t have the limitations of a traditional relay.
  • Offers safe charging between separate banks of 48V batteries.
  • Combining a 48V battery bank directly onto an independent 48V battery bank can be perilous due to differential voltages between banks.
  • A worst case scenario may be a 15S 48.0V lithium battery that is flat ~40V, being connected to a full 16S 51.2V lithium battery sat at 54V. This would result in vast current flows leading to BMS open circuit, meaning no charging would take place. A similar event may occur when simply connecting a full 51.2V battery onto an empty one.
  • The BB484830 offers current limiting and correct charging voltages for charging between an array of voltages 39V-60VDC. An example may be that you have a large 48V rack style storage battery that you use to charge up smaller capacity 48V batteries that are utilized in vehicles / electric boats / robots.
  • The BB484830 can be activated by any voltage signal between 8-80V on the ignition feed. There is also a selectable vibration sensor mode that shall engage the unit when the BB is in motion.
