It matches OEM part number S10-Li-144-5200 and slots into the battery bay without modification. Capacity is rated at 74.88Wh from the factory cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVac \/ Vac Max \/ Vac 2 \/ Vac 2 Pro compatibility:\u003c\/strong\u003e\n    All four models run the same 14.4V battery rail and share the S10-Li-144-5200 form factor. The BMS connector pinout and physical dimensions are identical across the range, so one cell covers the full lineup.\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 the Vac platform. The BMS handshake completed correctly, the unit accepted charge from the dock, and the protection circuit tripped at the expected overcurrent threshold during a simulated blockage event.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit for robot vacuums:\u003c\/strong\u003e\n    Do not leave the Yeedi on the charging dock indefinitely between uses. Continuous trickle charging degrades Li-ion cells faster than intermittent charge cycles. Charge to full, run the vacuum, then return it to the dock only when the battery needs replenishing.\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\"\u003eA blocked or dirty filter forces the motor to draw more current than rated to maintain suction. As the battery ages, voltage sag under that elevated load becomes significant — the robot appears to lose power early even though the indicator still shows charge remaining. The BMS reads real-time voltage, not state-of-charge percentage, so a sagging cell triggers low-power mode before the display catches up. Clean the filter first; if the drop persists with a clean filter, the cell is the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-cycle and then recovering\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a power-off event. When suction is restricted — partial blockage, a clogged brush roll, or a dense carpet edge — the motor draws a spike above the protection threshold and the BMS cuts output. The circuit resets after a few seconds and the robot restarts. Check the brush roll and filter before assuming the battery is at fault. If the cutouts continue with clear airflow, verify the replacement cell's BMS trip threshold matches the OEM spec at 14.4V nominal.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428000694362,"sku":"BWCS-EDT800VX-1","price":80.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428000727130,"sku":"BWCS-EDT800VX-2","price":93.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428000759898,"sku":"BWCS-EDT800VX-3","price":103.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EDT800VX-1.webp?v=1779933799","url":"https:\/\/batteryweb.com\/products\/yeedi-vac-robot-vacuum-replacement-battery-144v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
