AR Pasadena JS17650-Q2 Replacement Battery 11.1V 2000mAh

AR Pasadena / AWSBT10 — 11.1V Li-ion Replacement Battery (JS17650-Q2)

This is an 11.1V, 2000mAh Li-ion replacement battery for the AR Pasadena portable Bluetooth speaker. It fits the Pasadena, AWSBT10, AWSBT10BK, and Santa Clara models, plus two additional variants sharing the same battery bay and connector. Use the OEM part number JS17650-Q2 to confirm fitment before ordering.

• Pasadena and AWSBT10 series fitment: These models share a common 11.1V power rail, battery bay dimensions, and connector pinout. The BMS handshake between the speaker's charge controller and this cell pack matches the original factory spec, so charge and discharge thresholds behave as expected from the factory.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the AWSBT10 platform. The BMS held the upper cutoff at 12.6V and engaged low-voltage protection at approximately 9V, consistent with a standard 3S Li-ion configuration.
• Monthly discharge cycle for the Pasadena: The Pasadena is typically left on a desk or shelf and topped off before it drops below 50%. Do that every day and the fuel gauge drifts within three months. Let the pack discharge below 20% at least once a month before recharging to recalibrate the gauge and slow capacity fade on the Li-ion cells.

Bluetooth dropping at high volume on the Pasadena

At high volume, the amplifier draws a sharp current spike on top of the Bluetooth radio's steady draw. If the cell's internal resistance has risen — either from age or from shallow cycling — the combined load pulls the pack voltage down momentarily. The speaker's BMS reads that sag as a low-voltage event and throttles output, which kills the Bluetooth signal first before audio cuts. A fresh cell with lower internal resistance handles the combined amp and radio draw without sagging enough to trip the protection circuit.

Audio distorting before the battery indicator reaches empty

This happens when the pack can no longer hold voltage under amplifier load, even though the gauge still reads 20–30%. The amplifier clips because supply voltage has dropped below the threshold it needs for clean output — the distortion is the amp trying to push audio it doesn't have enough voltage to reproduce. The battery indicator lags behind because it reads resting voltage, not loaded voltage. If you hear clipping before the low-battery warning fires, the cell's capacity has faded and the pack needs replacing.
