Rode NTA572125 GO Receiver Compatible Battery 3.7V 320mAh

Rode GO Receiver / Go Transmitter — 3.7V Li-Polymer Replacement Battery (NTA572125)

This is a 3.7V 320mAh (1.18Wh) lithium-polymer cell that fits the Rode GO Receiver and Go Transmitter. Both units run on the same compact LiPo pack, making this a single replacement that covers either half of the Wireless GO system. Replace this cell when the original degrades and the unit can no longer hold a charge through a recording session.

• Wireless GO Receiver and Transmitter compatibility: Both units share the same NTA572125 cell footprint, voltage rail, and connector orientation. The BMS in each unit communicates charge state through the same three-contact pad arrangement, so one cell works across both devices without modification.
• Bench tested on actual hardware: We ran the cell through charge cycles on the GO Receiver and confirmed the BMS accepted the pack, reported charge state correctly, and held voltage above 3.5V under combined RF transmission and audio draw before tapering.
• First-use charge cycle on the GO Receiver: After fitting, charge the unit via USB until the LED indicator shows a full charge before using it for a recording session. The GO Receiver's onboard BMS needs one complete charge cycle to calibrate its remaining-charge reporting accurately — skipping this means the battery indicator may cut off unexpectedly mid-session.

Why the GO Receiver drops signal during active recording

The GO Receiver runs both the 2.4GHz RF front end and the audio processing simultaneously. Under that combined draw, a degraded or low-voltage cell sags below the BMS cutoff threshold faster than the battery indicator suggests. The result looks like a wireless dropout but is actually a voltage event inside the unit. A fresh cell at full charge handles the peak draw without sagging to cutoff.

Battery indicator shows full but GO Receiver shuts off after a few minutes

This happens when a replacement cell ships at storage voltage — typically around 3.6V — and the BMS has not yet completed a calibration cycle. The indicator reads the resting voltage as full, but the cell cannot sustain load. Charge the unit fully via USB before first use. After one complete charge-to-discharge cycle, the BMS recalibrates and the indicator tracks accurately against actual remaining capacity.
