It fits models 071478 and the Soundlink Revolve Plus across both generations. Voltage and cell format match the original pack exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRevolve+ and Revolve+ 2 compatibility:\u003c\/strong\u003e\n    Both generations share the same 7.4V cell configuration, connector pinout, and BMS handshake protocol. The fuel gauge and protection circuit communication remain identical between the two, so one battery covers both platforms without any hardware modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack on a SoundLink Revolve+ at high volume, cycling the amplifier and Bluetooth radio simultaneously. The BMS held stable under combined draw peaks and did not trip during the current spikes typical of loud playback bursts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMonthly discharge cycle on daily-use speakers:\u003c\/strong\u003e\n    If the Revolve+ sits on a desk and gets topped off before dropping below 50%, the fuel gauge drifts over time. Let the battery drop below 20% at least once a month before recharging to keep the cell calibration accurate and slow capacity fade.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBluetooth dropping at high volume on the Revolve+\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAt maximum volume, the amplifier and Bluetooth radio draw current simultaneously. On a worn or deeply discharged pack, combined load causes voltage sag that briefly pulls cell voltage below the radio module's operating threshold. The Bluetooth stack interprets this as a signal fault and drops the connection. A fresh 2600mAh pack maintains the voltage headroom needed to supply both loads at once without sagging into cutoff territory.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSpeaker won't wake from USB charging after sitting discharged for weeks\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the Revolve+ sits unused for an extended period, the cell can discharge below the minimum acceptance voltage for USB-C power delivery — typically around 2.5V per cell. The charger handshake fails because the BMS blocks charge input to protect the cell. Connect the USB-C cable and leave it undisturbed for 15–20 minutes. The BMS on this pack includes a low-voltage recovery mode that allows a trickle pre-charge to bring the cell back above 3.0V before switching to normal CC\/CV charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416212013146,"sku":"BWCS-BSE478SL-1","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416212045914,"sku":"BWCS-BSE478SL-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416212078682,"sku":"BWCS-BSE478SL-3","price":57.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BSE478SL-1.webp?v=1779760823","url":"https:\/\/batteryweb.com\/products\/bose-soundlink-revolve-replacement-battery-74v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
