It fits the 1C, Q7 Max, Q7 Max+, S5, and more than 24 additional Roborock models. When the original cell degrades, suction drops and cleaning cycles shorten — this battery restores the power supply to the motor and navigation board.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMulti-model fit across Roborock platforms:\u003c\/strong\u003e\n    The 1C, Q7 Max, Q7 Max+, and S5 series share the same 14.4V battery architecture, connector pinout, and BMS handshake protocol. Swapping between these platforms does not require firmware changes or adapter hardware.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full discharge-recharge sequences on a Roborock unit and monitored BMS communication. The protection board responded correctly to over-discharge cutoff and charge termination signals without throwing fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on robotic vacuums:\u003c\/strong\u003e\n    Do not leave the robot on the charging dock permanently. Continuous trickle charging is one of the fastest ways to degrade a Li-ion cell in this format. Charge to full, then remove the dock connection — or let the robot discharge before returning it to charge.\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 filter is partially blocked or the brush roll is restricted, the motor draws more current than rated. The BMS sees the voltage dip under that load and reduces output to protect the cell — the robot reads this as low power before the actual charge level is low. Clean the filter and check the brush roll for hair wrap before replacing the battery. If suction recovers after cleaning, the battery is not the fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-cycle then restarts on its own\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. Sustained restricted suction — from a clogged filter or jammed brush — forces the motor to pull current beyond the BMS threshold. The protection board cuts the circuit, then resets once current demand drops. The robot resumes as if nothing happened. Wash the filter, clear the brush chamber, and run a full cycle. If the cutout stops happening, the cell itself was never the problem.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427991257178,"sku":"BWCS-XMS510VX-1","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427991289946,"sku":"BWCS-XMS510VX-2","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427991322714,"sku":"BWCS-XMS510VX-3","price":115.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-XMS510VX-1.webp?v=1779933756","url":"https:\/\/batteryweb.com\/products\/roborock-1c-replacement-battery-144v-6800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
