It replaces OEM part A007032 and fits the same battery bay without modification. Capacity figure is taken directly from product data at 9.62Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBRV-PRO and BPRO5CB compatibility:\u003c\/strong\u003e\n    Both models share the same 3.7V single-cell architecture, identical connector pinout, and the same BMS handshake protocol — one battery covers both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the BRV-PRO's charge circuit and confirmed the BMS accepted the pack without fault flags.

The BRV-PRO's fuel gauge calibrates to the cell's actual capacity on first full cycle — skipping this step causes the indicator to show empty while charge remains.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the BRV-PRO battery reads full but audio cuts after extended play\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BRV-PRO uses a simple coulomb-counting fuel gauge that drifts when the cell is never fully discharged. Constant top-off charging — plugging in before the pack drops below 50% — causes the gauge to lose its reference point over time. The speaker's protection circuit then triggers a low-voltage cutoff at what looks like a mid-range charge reading. A single full discharge-to-shutdown followed by a full charge resets the reference and restores accurate reporting.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAudio distorting before the battery indicator reaches empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAt high volume, the BRV-PRO's amplifier draws sharp current spikes that cause the cell voltage to sag below the amplifier's clean operating threshold before the fuel gauge registers low. The result is audible clipping or distortion while the indicator still shows charge remaining. This is a voltage-sag issue, not a capacity issue — a fresh cell with good internal resistance reduces sag and pushes the distortion point lower. If the symptom appears consistently above 70% volume, check resting cell voltage under no load; it should read above 3.6V after a full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416211914842,"sku":"BWCS-BRV500SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416211947610,"sku":"BWCS-BRV500SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416211980378,"sku":"BWCS-BRV500SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BRV500SL-1.webp?v=1779760823","url":"https:\/\/batteryweb.com\/products\/braven-brv-pro-replacement-battery-37v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
