It replaces OEM part BP25220F. When the original cell degrades and suction drops noticeably before the battery indicator hits low, this swap restores the motor to its rated voltage draw.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVSS1800 motor platform:\u003c\/strong\u003e\n    The VSS1800 runs a brushless motor tuned to a 25.2V nominal rail. The BMS in this pack matches that voltage profile and uses the same connector and handshake as the factory cell, so the vacuum's power management reads charge state correctly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through sustained suction load on the VSS1800 motor. The BMS held the voltage rail steady through full discharge and responded correctly to the charger on reconnect — no error flags or refused charge cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit for the VSS1800:\u003c\/strong\u003e\n    Do not leave the VSS1800 sitting on the charging dock permanently. Continuous trickle charge through the dock accelerates capacity fade in the cells. Charge to full, then remove the vacuum 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 on carpet 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 VSS1800 motor hits resistance — thick carpet pile, a partial blockage, or a clogged filter — it draws more current than the rated load. A degraded cell cannot hold the voltage rail under that spike, so the motor slows and suction drops even though the battery gauge still shows charge remaining. Check and clean the filter first. If the symptom persists with a clean filter, the cell is the cause — resting voltage on a healthy 25.2V Li-ion pack should read at or above 24.0V after a full charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean then restarts after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a motor fault. When airflow is restricted — blocked filter, full dustbin, or a partial floor nozzle blockage — the motor works harder to maintain suction and draws current above the BMS threshold. The BMS trips to protect the cells, cuts power, and resets after a brief cooldown. The fix is to clear the restriction: empty the dustbin, clean the filter, and check the nozzle for debris. If the motor trips again on an unrestricted vacuum with a fresh filter, check that the replacement pack is fully charged to 25.2V before the next run.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428001874010,"sku":"BWCS-ERC180VX-1","price":69.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428001906778,"sku":"BWCS-ERC180VX-2","price":80.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428001939546,"sku":"BWCS-ERC180VX-3","price":88.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ERC180VX-1.webp?v=1779933799","url":"https:\/\/batteryweb.com\/products\/midea-vss1800-replacement-battery-252v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
