When the original battery no longer holds charge or suction drops off quickly, this unit restores full motor voltage. Capacity is 2600mAh (38.48Wh), matching the stock specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eR30, R30 Pro, and R35 fitment:\u003c\/strong\u003e\n    These three models share the same 14.8V battery bay, connector pinout, and BMS communication protocol — one battery cell pack covers all three without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on the R30 platform. The BMS handshake completed correctly, the motor spun up without triggering an overcurrent trip, and cell balancing held within spec across multiple cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on the R30 series:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock continuously. The R30 series does not interrupt trickle current once full, so permanently docked units develop capacity fade significantly faster. Charge to full and remove the vacuum from the dock.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSuction dropping before the battery indicator reaches low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage sag issue, not a capacity issue. When the motor pulls hard — especially on carpet or during a blockage — cell voltage dips below the BMS threshold before the indicator registers low charge. The BMS reads that sag as a protection event and throttles motor power. Check the filter first: a partially blocked filter forces the motor to draw above rated current, which accelerates the sag. Clean or replace the filter, then check whether suction holds at consistent power through a full run.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean and then recovers after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. Sustained restricted airflow — blocked filter, clogged brush roll, or a sealed nozzle — pushes motor draw past the BMS overcurrent limit. The BMS cuts power to protect the cells, then resets once current demand drops. The fix is clearing the restriction, not replacing the battery again. After clearing, verify the battery rests at 16.4V or above on a multimeter before the next run — a cell resting below 14.8V after a full charge indicates a cell that needs replacement.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428013080666,"sku":"BWCS-MVS500VX-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428013113434,"sku":"BWCS-MVS500VX-2","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428013146202,"sku":"BWCS-MVS500VX-3","price":48.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MVS500VX-1.webp?v=1779933850","url":"https:\/\/batteryweb.com\/products\/puppy-r30-replacement-battery-148v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
