It restores power to the autonomous cleaning robot when the original cell has degraded past usable capacity. Voltage and connector match the original pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBobSweep Pro, PetHair, Standard, and Junior compatibility:\u003c\/strong\u003e\n    These models share a common 14.8V four-cell Li-ion architecture with the same connector pinout and BMS communication protocol. One pack covers the full group without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran charge and discharge cycles on this cell using the BobSweep dock charger. The BMS accepted the handshake from the dock without fault codes, and cell balancing across all four cells stayed within 20mV variance at full charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on BobSweep units:\u003c\/strong\u003e\n    Do not leave the robot sitting on the dock between every session as a default state. Continuous trickle charging through the dock accelerates capacity fade on Li-ion packs in this voltage range. Charge to full, then remove from the dock until the next use.\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 on the BobSweep Pro\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage sag issue, not always a dead battery. When the motor draws peak current — particularly on carpet or when the filter is partially blocked — cell voltage drops sharply under load. The BMS reads this transient voltage drop as a low-battery condition and throttles output before the indicator catches up. A clean filter reduces motor draw and brings peak current back within the cell's delivery range. Check and clear the filter first before concluding the battery has failed.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBobSweep motor cuts out mid-cycle, then recovers after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip. The BobSweep's suction motor pulls a sustained high-current draw when airflow is restricted — blocked brush roll, clogged filter, or jammed intake. The BMS trips the output circuit to protect the cells, then resets once current demand drops. The recovery pause is the BMS re-enabling the output after the overcurrent condition clears. Clear the blockage, confirm the brush roll spins freely, and verify filter airflow before reinstalling the battery.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428013932634,"sku":"BWCS-MVS500VX-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428013965402,"sku":"BWCS-MVS500VX-2","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428013998170,"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\/bobsweep-pro-sjp110020-replacement-battery-148v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
