It uses an INR18650 MH1-4S1P-SC cell configuration — four 18650 cells in series, one parallel. Fit this when the original pack no longer holds charge or the vacuum loses suction well before the indicator drops.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVIOMI V3 and Mi Robot Vacuum Mop P platform:\u003c\/strong\u003e\n    These models share the same 14.4V battery rail, connector pinout, and BMS handshake protocol. The replacement pack carries the same cell arrangement, so the vacuum's charge management circuit recognises it without reconfiguration.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through full charge and discharge cycles on the VIOMI platform. The BMS responded correctly to trickle-charge termination and triggered overcurrent protection as expected under sustained motor load at blocked-filter conditions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on cordless vacuums:\u003c\/strong\u003e\n    Do not leave the VIOMI on the charging dock permanently. Continuous dock charge applies a trickle current to Li-ion cells that accelerates capacity fade faster than cycled charging. Charge to full, then remove the vacuum 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 VIOMI V3\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the motor draws more current under a partially restricted airpath — a clogged filter or tangled brush roll raises resistance, and the cell voltage sags under that load before the indicator circuit registers a low-battery event. The BMS reads pack voltage, not motor load, so it won't flag a problem until voltage drops below its threshold. Clean the filter and clear the brush roll first — if suction recovers, the issue was airpath restriction, not the battery. If the pack still sags under a clear airpath, cell degradation is the cause and replacement is the fix.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean then recovers after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a power button fault. When suction is sustained against a blockage or a fully clogged filter, current draw spikes beyond the BMS protection threshold and it disconnects the pack to prevent cell damage. The pack recovers automatically once current demand drops — which is why the vacuum restarts after a short pause. Clear any blockage, clean or replace the filter, and restart. If the cutout repeats on a clear airpath, check pack voltage at the terminals; a degraded cell group will show below 13.5V at rest on a fully charged pack.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427950329946,"sku":"BWCS-XMR200VX-1","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427950362714,"sku":"BWCS-XMR200VX-2","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427950395482,"sku":"BWCS-XMR200VX-3","price":60.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/batteryweb.com\/products\/xiaomi-viomi-v3-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
