It replaces OEM part numbers BP14435A and BP14433A. Fit the battery and the vacuum runs at full suction power again — no tools required.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ei5 and i9 EYE platform compatibility:\u003c\/strong\u003e\n    These models share the same 14.4V battery rail, connector pinout, and BMS handshake requirements. One cell pack covers the full range listed above without adapter modifications.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack on the i5 under sustained motor load. The BMS held voltage within spec across both hard floor and carpet modes, and the protection circuit responded correctly to simulated blockage overcurrent without nuisance tripping.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on the Midea i5:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock between uses. The i5 dock does not cut trickle charge once full. Continuous float charging degrades cell capacity faster than normal cycle wear. Charge to full, then remove the vacuum from the dock and store it separately.\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 Midea i5\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the motor draws more current than the BMS expects — most often caused by a partially blocked filter, not a weak battery. A restricted airflow path forces the motor to work harder, pulling current above the pack's rated draw and triggering a soft voltage sag. The vacuum feels underpowered even though the indicator still shows charge remaining. Clean or replace the filter first, then retest — a clear airflow path brings motor draw back within the battery's rated output window.\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 faulty motor. When suction is restricted — blocked filter, full dustbin, or a jammed brush roll — the motor surges to maintain airflow and current spikes past the protection threshold. The BMS shuts the output rail, the motor stops, and once the pack cools slightly the circuit resets. Fix the restriction first. If cutout continues on a clear filter, check that pack voltage under load does not drop below 12.5V — a pack that sags past that point under normal draw needs replacement.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427985227866,"sku":"BWCS-SMR500VX-1","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427985260634,"sku":"BWCS-SMR500VX-2","price":52.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427985293402,"sku":"BWCS-SMR500VX-3","price":57.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMR500VX-1.webp?v=1779933696","url":"https:\/\/batteryweb.com\/products\/midea-i5-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
