It fits the stick vacuum's battery bay directly and connects to the same BMS communication circuit the motor controller expects. Capacity figures come from product data — 74.88Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRoidmi Eve Plus and Viomi platform fit:\u003c\/strong\u003e\n    These models share a common 14.4V cell architecture, connector pinout, and BMS handshake protocol. One battery pack covers the full group because the motor controller reads the same charge-state signal across all four variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through sustained motor load on the Eve Plus and confirmed the BMS held the 14.4V rail steady through multiple cleaning modes. Overcurrent protection tripped correctly when the airway was blocked, then reset cleanly on clearing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on the Eve Plus:\u003c\/strong\u003e\n    Leave the vacuum seated on the charging dock only until the pack reaches full charge, then remove it. Cordless vacuums parked on the dock indefinitely receive a low-level trickle that accelerates capacity fade — the Eve Plus charger does not switch to a true maintenance mode once full.\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  \u003cp class=\"bpw-desc-p\"\u003eThis is not always a battery fault. When the Eve Plus filter is partially clogged, airflow restriction forces the motor to draw more current than rated. The BMS reads the voltage sag caused by that overcurrent and interprets it as a depleted pack — triggering a power reduction before the indicator shows low. Clean the filter first. If suction still drops with a clean filter and a charged pack, the cell voltage under load has likely degraded below the 13.5V threshold the motor controller needs to maintain full power.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean and then recovers after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a wiring fault. It happens when sustained suction against a blockage — carpet fringe, debris catch, or a clogged cyclone — pulls current beyond the pack's continuous discharge limit. The BMS cuts the output to protect the cells, waits a few seconds, then resets. Clear any obstruction and check that the cyclone separator is fully seated. If trips repeat on an unobstructed machine, verify the pack is resting at or above 14.4V on a full charge before use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427996172378,"sku":"BWCS-PCM710VX-1","price":70.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427996205146,"sku":"BWCS-PCM710VX-2","price":83.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427996237914,"sku":"BWCS-PCM710VX-3","price":92.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PCM710VX-1.webp?v=1779933755","url":"https:\/\/batteryweb.com\/products\/xiaomi-roidmi-eve-plus-replacement-battery-144v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
