Sterling Power Battery-to-Battery Chargers

Part # BB484830 DC to DC Smart Battery Charger.

Why wait to arrive at your destination to plug in your battery charger?

Now you can smart charge the housebank in your Boat, Tow Camper, Boat in tow, Sprinter or Custom Van while driving down the road or on the water. This charger correctly calculates the batteries or bank of battery 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.
 

DC Powered Smart Charger, perfect for smart charging your auxillary battery bank in a Truck, Mercedes Sprinter or Ford Transit van, Doesnt have the limitations of a tradional relay. 

- Buck Boost design, offering high efficiency (95-98%)
- Simple installation and setup
- Current limiting charger
- Lithium safe
- Smart Alternator/Euro 6+ compatible
- Ignition feed or Vibration Sense modes can be used for turning the charger on and off.
- 6 preset battery types
- 6 self recovering protections
- Low temperature trip for Lithium Ion batteries

48V to 48V DC to DC Charger 

(available now)

offers safe charging between seperate banks of 48V batteries. 

BB484830 - 48V to 48V DC DC charger ~1600W. 30A. ideal for charging between 2 sets of 48V batteries. Lithium or lead acid. 

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 utilised 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.
