AUDIOROOT eSMART TRIO – Advanced Smart Power Distribution System

Estimated delivery time: 1–2 weeks.

Product description

The AUDIOROOT eSMART TRIO is a professional‑grade, portable power distribution system specifically engineered for location sound recordists. Designed with adaptability, reliability, and data intelligence in mind, it supports up to three independent power sources — including smart batteries and external DC/AC power supplies — and efficiently distributes power via 8 DC outputs and 2 USB ports.

Whether you're running a mobile sound bag or a cart‑based setup, the eSMART TRIO ensures seamless power delivery, intelligent battery monitoring, and hot‑swappable redundancy, offering unmatched flexibility for critical field operations.

Smart & Seamless Power Management

• 3 power inputs (TA4M connectors) supporting multiple configurations:

  • Single smart battery

  • Dual batteries with load sharing

  • External DC input with battery backup

  • High‑priority battery with backup

  • Triple‑battery cascading configuration

• Hot‑swapping supported — connect or remove power sources without interruption

• Intelligent power source prioritization with auto‑switching and high‑priority routing

• smBUS data passthrough for real‑time battery data aggregation and monitoring

• Overcurrent and short‑circuit protection with automatic retry every 40 seconds until the fault clears

Output Connectivity & Control

• 7 Hirose‑compatible DC outputs:

  • 6 on rear (4 main, 2 switchable auxiliary)

  • 1 front panel auxiliary (AUX2)

• 1 TA4F Switchcraft‑compatible output:

  • Provides aggregated smBUS data from all connected batteries

  • Ideal for Sound Devices mixers/recorders or other smart‑battery‑aware devices

• 2 USB ports on the front panel:

  • USB‑C Power Delivery up to 45W (5V/9V/12V/15V/20V up to 3A)

  • USB‑A Quick Charge 3.0 up to 15W (5V/9V/12V)

• Output control via 2 LED‑illuminated pushbuttons

  • Independently toggle AUX1/AUX2 outputs

  • Visual status memory retention

Real‑Time Data Visualization

Equipped with three OLED displays for complete power transparency:

• 1 color OLED (96 × 64 px) showing combined system metrics, estimated runtime, current draw, and fault warnings

• 2 blue OLEDs (128 × 28 px) showing individual battery state‑of‑charge, temperature, cycle count, and cell voltages

• Battery serial numbers and temperature (°C/°F) accessible via quick cycling

• Icons indicate external power, high‑priority status, and output states

Construction, Mounting & Updates

• Robust aluminum housing

• Compact dimensions: 83 × 40 × 94 mm

• Weight: 300 g (without belt clip)

• 10 × M3 threaded holes for flexible rigging

• Mini‑USB port (internal) for firmware upgrades

• Belt clip included for sound bag integration

Power Source Compatibility & Best Practices

• Fully compatible with AUDIOROOT smart batteries and third‑party 2054‑style smart batteries

• Firmware v1.1+ allows operation with non‑smart batteries (voltage display only)

• Maximum total current: 11.5A (165W @ 14.4V)

  • Recommended max draw: 8A with 2054‑style batteries

  • Use 2 × Li‑96neo for full performance (each rated 11.75A)

• TA4F output limited to 5A

• Hirose outputs limited to 2.5A each
