It replaces OEM part GW002-A2-4S1P, the factory cell pack that powers the D6s motor and suction system. When the original pack can no longer hold a full charge, this replacement restores the vacuum to working condition.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eD6s motor system fit:\u003c\/strong\u003e\n    The D6s runs a brushless motor at a 14.4V nominal rail. This pack matches that rail and uses the same 4S1P cell configuration as the factory unit, so the BMS can communicate correctly with the vacuum's motor controller without triggering a voltage mismatch cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on the D6s platform. The BMS handled full draw under hard-floor and carpet modes without tripping overcurrent protection, and the cell voltage balanced correctly across all four cells at the top of charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging on the D6s:\u003c\/strong\u003e\n    Do not leave the D6s sitting on its charging dock continuously. Charge the pack to full, then remove it from the dock. Persistent trickle current from the dock accelerates capacity fade in Li-ion cells faster than regular charge-and-use cycles do.\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 D6s\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the motor is working harder than rated — usually because the filter is partially blocked. A restricted airflow path forces the motor to draw higher current to maintain suction, which pulls cell voltage down faster than normal discharge. The BMS reads the sagging voltage as a low-battery condition and begins reducing power to the motor before the display indicator catches up. Clean or replace the D6s filter first, then retest — if the problem disappears, the battery was not the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eD6s motor cuts out mid-clean and then recovers after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead cell. When sustained suction restriction — a blocked nozzle or clogged filter — pushes motor draw past the BMS current threshold, the pack cuts power to protect the cells. After a brief rest, the BMS resets and the vacuum runs again. Clear the blockage at the nozzle and wash the filter before putting a replacement battery in. If the cutout continues with a clean airflow path, check that the pack contacts are fully seated and that contact voltage at the terminals reads at least 14.0V under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426467151962,"sku":"BWCS-CPR301VX-1","price":505.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426467184730,"sku":"BWCS-CPR301VX-2","price":605.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426467217498,"sku":"BWCS-CPR301VX-3","price":680.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPR301VX-1.webp?v=1779933287","url":"https:\/\/batteryweb.com\/products\/ultenic-d6s-replacement-battery-144v-3350mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
