It fits the G1 MI Robot, MI-G1, Robot Vacuum-Mop Essential G1, and MJSTG1 models. It powers the drive motors, suction fan, and onboard navigation hardware through full cleaning cycles.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG1 and MJSTG1 platform fit:\u003c\/strong\u003e\n    These models share the same 14.8V four-cell Li-ion architecture, connector pinout, and BMS communication protocol. The same battery pack runs across the G1 and Essential G1 variants because Xiaomi standardised the cell bay and charge circuit on this platform.\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 a G1 unit. The BMS handshake initialised correctly, charge acceptance was normal, and the protection circuit tripped as expected under simulated overcurrent — then reset cleanly on the next charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit for this vacuum:\u003c\/strong\u003e\n    Do not leave the G1 sitting on the dock permanently between uses. Continuous trickle charge on this pack's BMS causes measurable capacity fade over time. Charge to full, then remove from the dock until the next cleaning 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 shows low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is voltage sag under load, not a charge level problem. When the filter is partially blocked, the suction motor draws more current than rated to maintain airflow. The pack voltage dips under that elevated load, and the G1 interprets the sag as reduced capacity even though the battery still holds a reasonable state of charge. Clean or replace the filter first — if suction recovers, the battery was not the root cause. If sag continues with a clean filter, the pack has lost enough cell capacity to drop below the motor's working voltage threshold under normal draw.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-cycle then recovers on its own\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a loose connection. Sustained restricted airflow — usually a clogged filter or a tangled brush roll — forces the motor to spike current beyond the BMS protection threshold. The BMS shuts the output, the motor stops, and after a short thermal or timer reset window the circuit re-enables. The fix is not the battery — clear the brush roll, tap out the filter, and run again. If the cutout persists with unrestricted airflow, verify pack voltage under load sits above 13.5V; below that the pack needs replacement.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428013408346,"sku":"BWCS-MVS500VX-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428013441114,"sku":"BWCS-MVS500VX-2","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428013473882,"sku":"BWCS-MVS500VX-3","price":48.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MVS500VX-1.webp?v=1779933850","url":"https:\/\/batteryweb.com\/products\/xiaomi-g1-mi-robot-replacement-battery-148v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
