eSMART BG-DU-REG

AUDIOROOT eSMART BG‑DU‑REG – Advanced Smart DC Power Distributor (Regulated Outputs)

Estimated delivery time: 1–2 weeks.

Product description

The eSMART BG-DU 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.

Additional Features – BG‑DU‑REG Variant

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 isolated 12V / 12W outputs (Hirose connectors) – helps resolve ground loop issues

• 1 × 9V / 18W output (Hirose connector) – suitable for wireless receivers/transmitters

• Compact and lightweight: 300 g, 85 × 120 × 30 mm

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.
