It replaces OEM part P2051-4S1P-ZM and fits the Sweeping Vacuum Cleaner 2C platform. Capacity is rated at 46.08Wh — matched to the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e2C platform compatibility:\u003c\/strong\u003e\n    The STYTJ04ZHM and Sweeping Vacuum Cleaner 2C share the same 14.4V four-cell series configuration and battery bay connector. The BMS communicates charge state to the vacuum's LED indicator, so the indicator reads accurately with this pack.\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 2C motor platform. The BMS held overcurrent protection correctly under simulated blockage loads and allowed full recharge without faulting.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on the Mijia 2C:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock continuously. The 2C trickle-charges when docked and full — this accelerates capacity fade in Li-ion cells over weeks of standby. Charge to full, then remove from the dock.\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 2C\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Mijia 2C motor draws significantly more current when the filter is partially blocked — the cells sag under load even when charge level reads normal. At elevated draw, cell voltage can drop below the BMS cutoff threshold before the indicator registers low. Clean the filter first and test again. If suction recovers immediately after a filter clean, the battery is not the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out and then recovering mid-clean\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When the vacuum sustains restricted suction — blocked nozzle, clogged filter, or heavy carpet fibres — the motor pulls above rated current long enough to trigger the BMS protection circuit. The pack shuts the output, then recovers once current demand drops. Clear the blockage, then power the vacuum on again. If trips continue on a clean filter with this replacement pack, check that resting pack voltage reads 16.4V or above after a full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427957014618,"sku":"BWCS-XMP400VX-1","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427957047386,"sku":"BWCS-XMP400VX-2","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427957080154,"sku":"BWCS-XMP400VX-3","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-XMP400VX-1.webp?v=1779933588","url":"https:\/\/batteryweb.com\/products\/mijia-2c-replacement-battery-144v-3200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
