Shure SBRC-US Rack Battery Charger, Compatible with Shure rechargeable batteries AXT910, AXT920 and SB900A.

Product Overview

The Shure SBRC Battery Rack Charger is a touring-ready 1RU rack-mount charging station that accepts up to four interchangeable charging modules, supporting up to 8 Shure rechargeable Li-Ion batteries in any combination across the AXT910, AXT920, SB900-series, SB910, SB910M, and SB920/SB920A battery families. Its comprehensive front panel display reports charge status, time-to-full, battery health, cycle count, and temperature per bay, while Ethernet connectivity enables remote monitoring via Shure Wireless Workbench—making it the centralized battery management hub for high-channel-count commercial AV and touring wireless deployments.

Product Description

The SBRC's modular architecture sets it apart from fixed-format chargers: AV integrators can populate each of the four module bays with any combination of SBC-AX (SB900-series), SBM910 (SB910), SBM910M (SB910M), or SBM920 (SB920/SB920A) modules, allowing a single 1RU rack unit to service mixed wireless fleets spanning ULX-D, QLX-D, Axient Digital, PSM 900, and PSM 1000 systems. A deep discharge recovery mode automatically rescues batteries discharged below 3.0 V. Storage Mode charges or discharges all batteries to 3.8 V for long-term storage. The integrated cooling fan has three configurable speed modes (Low, High, Automatic) to balance noise and thermal performance. Note: charging modules are sold separately; this listing is for the SBRC-US rack charger chassis only.

Key Features

• 4-Module, 8-Battery Capacity — Accepts up to 4 interchangeable charging modules in any combination, supporting up to 8 Li-Ion batteries per chassis across multiple Shure battery families.
• Universal Battery Compatibility via Modules — Compatible with SBC-AX (SB900-series), SBM910 (SB910), SBM910M (SB910M), and SBM920 (SB920/SB920A) modules, enabling mixed-fleet charging in a single rack unit.
• Comprehensive Front Panel Display — LCD screen shows charge percentage, time-to-full, battery health percentage, cycle count, and temperature per bay without requiring network access.
• Ethernet-Enabled Wireless Workbench Monitoring — 10/100 Mbps Ethernet port enables remote battery monitoring and charger management via Shure Wireless Workbench software.
• Deep Discharge Recovery — Automatically detects batteries discharged below 3.0 V and applies reduced current to restore cells before resuming normal charging.
• Storage Mode — Charges or discharges all batteries to 3.8 V for optimal long-term storage; supports fleet battery health between tour legs or production seasons.
• Configurable Cooling Fan — Three fan modes (Low, High, Automatic) allow noise and thermal performance to be balanced for rack environments with varying airflow.
• Energy Efficiency Mode — Disables display backlight and network functionality to reduce power consumption during unmonitored charging cycles.
• Steel and Extruded Aluminum Housing — Touring-grade construction rated for continuous commercial AV and live production environments.

Frequently Asked Questions

Do charging modules come included with the SBRC-US?
No. The SBRC-US is the rack charger chassis only. Charging modules are sold separately: SBC-AX for SB900-series batteries, SBM910 for SB910, SBM910M for SB910M, and SBM920 for SB920/SB920A. Up to four modules in any combination can be installed.

What battery types can the SBRC-US charge?
With the appropriate modules installed, the SBRC-US charges AXT910, AXT920, SB900-series (SB900A/B/C), SB910, SB910M, SB920, and SB920A batteries—covering the full range of Shure Axient Digital, ULX-D, QLX-D, PSM 900, and PSM 1000 wireless systems.

How does the SBRC-US connect to Wireless Workbench?
Connect the SBRC-US to your network via the rear Ethernet port. Open Wireless Workbench and select the correct network interface; the charger appears in the Inventory tab with per-bay charge status, battery health, cycle count, and temperature.

What is deep discharge recovery mode?
When the SBRC detects a battery discharged below 3.0 V, it automatically applies a reduced charge current to recover the cell before resuming normal charging. If the battery cannot be recovered within 30 minutes, the display shows “Recovery Failed”. To prevent deep discharge, Shure recommends using Storage Mode periodically for batteries not in regular use.

What warranty is included?
Shure provides a limited 1-year manufacturer warranty on the SBRC-US. Contact Creation Networks for commercial procurement and volume support options.
