Audioroot eSMART BG-DU Compact DC Power Distribution Box

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.
