eSMART BG-DU

Universal power distributor with fuel gauge

The eSMART BG-DU is a compact and lightweight powering box with 8 protected outputs, 3 locking switches and a full featured fuel gauge.

This product was designed for use in large sound bags or small location carts. The power distributor can be connected to any battery type (SLA, NI-MH or LI-ION) and the fuel gauge provides all the informations required to monitor the battery’s state of charge (voltage, current, power, etc…).

The eSMART BG-DU uses an internal coulomb counter and a calibration routine to measure the battery’s true capacity and display it’s remaining capacity in real time. This power distributor is also fully compatible with our full line of Li-XXwh smart batteries. A stainless steel clip is included and can be mounted on the top or bottom of the unit for easy attachment in a sound bag.

  • Real time monitoring of the battery’s SOC : remaining capacity (%), run time estimation, battery voltage, power consumption, power and coulomb counter
  • 8 switchable outputs using 3 locking switches
  • Polyswitch 2.5A resetable fuses on each output
  • A blinking LED indicates when the battery capacity falls below 10 %
  • Compatible with any battery ranging from 6 to 24V
  • Stainless steel clip included
  • Compact and lightweight : (129g , 85x75x30mm)

Important note : A 4 conductor battery input cable is required for eSMART operation (i.e when connecting eSMART batteries to the BG-DU). This cable is sold separately under reference eHRS4-OUT-4W. The 2 conductor Hirose battery output cable available under reference eHRS4-OUT will not enable battery data communications between the eSMART batteries and the BG-DU. Please contact us or your dealer for more information.

Note to Hawk-Woods products users : The wiring of Hawk-Woods products is incompatible with the BG-DU or BG-DU-REG out of box.  On these products the internal pins of the Hirose male plugs are tied together 2 by 2 : pins 1 and 2 / pins 3 and 4. When using the BG-DU or BG-DU-REG pins 2 and 3 of the male Hirose plug connected to the unit’s input must be left unconnected as these are used for communication with smart batteries. Hawk-Woods users can solve this issue by rewiring the male Hirose plug (leaving pins 2 and 3 un-connected) or by removing 2 solder jumpers inside the BG-DU or BG-DU-REG. Please contact us for more details.

Max battery capacity : The BG-DU can handle standard (non smbus) batteries from other manufacturers up to 40Ah. A special version capable of handling batteries up to 200Ah can be delivered upon request.

Max current draw: The BG-DU can easily and safely handle a total current draw of 5 Amps.
