It replaces OEM part BRR-1P4S-2600S and restores the robot's ability to complete autonomous cleaning cycles. When the original cell degrades, the vacuum either cuts out mid-run or fails to hold a charge long enough to finish a mapped route.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eC10 and E20 platform compatibility:\u003c\/strong\u003e\n    The C10 (C102-00) and E20 (E202-00) share the same battery bay dimensions, connector pinout, and BMS handshake protocol. One cell fits both lines because Xiaowa used a common power architecture across this generation of robot vacuums.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on compatible hardware. The BMS communicated correctly with the charger, accepted a full charge without fault codes, and held voltage within spec across multiple depletion cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging discipline:\u003c\/strong\u003e\n    Do not leave the Xiaowa on the dock permanently between uses. Continuous trickle charging accelerates capacity fade in this cell chemistry. Charge the robot fully, then remove it from the dock until the next scheduled run.\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\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage sag issue, not a capacity issue. When the filter is partially blocked, the suction motor draws more current than rated to maintain airflow. That elevated draw pulls cell voltage down early, causing the robot to reduce motor speed or cut suction before the battery gauge registers low. Clean the filter and check the dustbin before assuming the battery is at fault. A healthy cell under normal motor load holds voltage steady well past the halfway point of a run.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRobot powers on but won't accept a charge after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the Xiaowa sits on the dock but the charging indicator never activates after fitting a replacement cell, the BMS may have entered a locked state from deep discharge. This happens when the original battery was left fully depleted for an extended period. Place the robot on the dock and leave it connected for at least 30 minutes without moving it — some BMS units require a low-current pre-charge phase before the main charge cycle triggers. If the indicator still does not activate, verify dock contact pins are clean and making firm contact with the robot's receiver pads. The cell should register above 10V at the terminals before a standard charge cycle will initiate.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427981688922,"sku":"BWCS-XMT400VX-1","price":57.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427981721690,"sku":"BWCS-XMT400VX-2","price":66.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427981754458,"sku":"BWCS-XMT400VX-3","price":73.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-XMT400VX-1.webp?v=1779933696","url":"https:\/\/batteryweb.com\/products\/xiaowa-c10-replacement-battery-144v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
