Shure SBC203 — Dual-Bay Charging Station for SB903 Batteries (QLX-D / ULX-D)

The Shure SBC203 is a dual-bay charging station for Shure rechargeable wireless transmitter batteries — specifically the SB903 used in QLX-D and ULX-D wireless systems. Charges two batteries in 3 hours simultaneously, with LED status indicators for each bay.

Why use rechargeable batteries vs disposable AAs: A venue running 4-8 wireless channels through hundreds of shows per year goes through enormous quantities of AA batteries. SB903 rechargeables pay for themselves quickly, deliver consistent voltage throughout the show (vs alkaline AAs that taper off), and integrate with Shure's runtime telemetry so the system reports exact remaining minutes.

Specifications:

• Charges 2x Shure SB903 lithium-ion rechargeable batteries
• Full charge in approximately 3 hours
• LED indicators show charge status per bay
• Compatible batteries: SB903 (for QLX-D and ULX-D systems)
• Includes power supply
• Daisy-chain capable — multiple SBC203 units can be linked for larger systems

Note on system compatibility: The SB903 batteries fit QLX-D and ULX-D handheld and bodypack transmitters. For SLX-D systems, the rechargeable equivalent is the SB904 — different battery, different charger (SBC10-100 or similar).

Ideal for: Venues running multiple Shure QLX-D / ULX-D wireless channels, churches and theaters operating on tight maintenance budgets, and AV rental companies needing predictable wireless runtime.
