Audioroot eSmart BG-DU Power Distributor
The Audioroot eSmart BG-DU Power Distributor is a compact, lightweight, and intelligent power distributor designed for demanding audio setups in large sound bags or compact location carts. Featuring 8 switchable, protected outputs , a real-time fuel gauge, and wide battery compatibility , it delivers reliable and efficient power management in the field.
Thanks to its integrated coulomb counter and advanced monitoring system, the BG-DU offers precise, real-time insight into battery status: remaining capacity (%), runtime estimation, voltage, current, and power consumption. It is fully compatible with all eSMART Li-XXwh and Li-neo smart batteries , enabling enhanced communication when used with the appropriate 4-wire input cable.
The eSMART BG-DU stands out as the only portable power distributor on the market equipped with a true coulomb counter and battery capacity learning routine. Unlike basic voltage-based monitoring systems, the BG-DU analyzes actual current flow over time to accurately learn and track the true capacity of any connected battery, even non-smart models (SLA, NiMH, or standard Li-Ion). This advanced approach allows the BG-DU to provide reliable runtime predictions and real-time state-of-charge monitoring, ensuring sound professionals can confidently manage power—even without using SMBus or smart battery technology.
Key features include:
- 8 outputs, switchable via 3 locking switches
- 1 x unfused output with SMBus pass thru
- Polyswitch 2.5A resettable fuses on all other outputs
- Smart fuel gauge with real-time battery diagnostics on a full color OLED display
- Visual low battery warning: blinking LED below 10% capacity
- Operates with 10-24V battery sources (SLA, NiMH, Li-Ion)
- Compact & rugged (129g, 85×75×30mm) with stainless steel clip for flexible mounting
- Max current draw: 5 Amps
- Max battery capacity: up to 40Ah (200Ah optional variant on request)
The BG-DU-REG variant includes all the features of the standard BG-DU, with the addition of three regulated and isolated outputs—ideal for eliminating ground loop noise and powering sensitive wireless gear.
Additional regulated outputs:
- 2 x Isolated 12V / 12W outputs (via Hirose connectors) – helps resolve ground loop issues
- 1 x 9V / 18W output (via Hirose connectors) – suitable for wireless receivers/transmitter
- Compact and lightweight: (300g, 85×120×30mm)
Whether you’re powering a complex location sound setup or need precision monitoring in the field, the BG-DU and BG-DU-REG offer rugged, smart, and flexible solutions trusted by sound professionals worldwide.
