Virtuoso Void RGB Replacement Battery 3.7V 1200mAh

Virtuoso Void RGB / RGB Wireless SE — 3.7V Li-Polymer Replacement Battery (AEC524050)

This is a 3.7V, 1200mAh Li-Polymer replacement battery for the Virtuoso Void RGB and Void RGB Wireless SE wireless gaming headsets. It slots directly into the headset housing and powers both the audio drivers and the wireless radio. Use the capacity figure from the product data — 1200mAh / 4.44Wh — as your reference spec.

• Void RGB and Wireless SE compatibility: Both models share the same cell footprint, connector pinout, and BMS handshake protocol. The AEC524050 cell dimensions — 52.80 x 39.80 x 5.00mm — match the cavity in both variants without modification.
• Bench tested on actual hardware: We cycled this cell through combined audio and 2.4GHz radio draw on the bench. The BMS held voltage above the low-cutoff threshold across sustained use and responded correctly to the base station charge controller.
• First charge after fitting: Seat the headset in the base station and run a full charge cycle before use. The base station needs to complete one full charge handshake with the new cell before its talk-time estimate reads accurately.

Why the Void RGB cuts out mid-session on a fresh battery

The Void RGB runs its audio DSP and 2.4GHz transmitter simultaneously, which creates a combined current draw that spikes during loud audio passages and wireless retransmits. A new cell at partial state of charge can hit the BMS low-voltage cutoff during one of these spikes before the gauge registers low. After one or two full charge-discharge cycles, the BMS calibrates to the actual cell capacity and the cutoffs become more accurate. If it cuts out immediately after charging, check that the base station contacts are clean — a resistive connection will cause an incomplete charge despite the LED showing full.

The Void RGB base station handshakes with the battery BMS on first contact to verify cell voltage is within its accepted intake range. If the replacement cell has been stored at a low voltage — below roughly 3.0V — the base station may refuse to initiate charging and flag an error. Remove the headset, leave it off the base for 30 seconds, then reseat it firmly so all charge contacts engage. If the error persists, use a compatible USB charger to bring the cell above 3.2V before returning it to the base.
