It replaces OEM part numbers BP14435A and BP14433A. Fit it when the original pack no longer holds charge or the vacuum loses suction before the indicator reaches low.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ei5 series platform compatibility:\u003c\/strong\u003e\n    The i5, i5 Young, i5 Extra, and i9 EYE all share the same 14.8V battery rail, connector format, and BMS handshake protocol. One pack covers all four models without modification.\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-discharge cycles on an i5 unit. The BMS held voltage within spec under sustained motor load, triggered correctly at low-cell cutoff, and accepted charge from the standard Midea dock without error codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on cordless vacuums:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock permanently. Continuous dock charge causes capacity fade significantly faster than charging only when depleted. 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 i5\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe i5 motor draws more current under restricted airflow — a partially blocked filter forces the motor to work harder, pulling the cell voltage down faster than normal operation would. The BMS reads this as approaching cutoff and reduces power to the motor before the indicator registers low. The vacuum feels like it's losing suction, but the battery may still have significant charge remaining. Clean or replace the HEPA and pre-filter first, then test suction under normal load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-clean and recovering after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When the vacuum runs over heavy carpet or a blockage restricts the airflow, current draw spikes above the BMS threshold and it cuts the output to protect the cells. The BMS resets after a brief cooling period, which is why the vacuum starts again a few seconds later. Clear any blockage, check that the filter is clean, and confirm cell voltage reads above 13.5V under no-load before ruling out a failing pack.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427979657306,"sku":"BWCS-SMR510VX-1","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427979690074,"sku":"BWCS-SMR510VX-2","price":74.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427979722842,"sku":"BWCS-SMR510VX-3","price":83.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMR510VX-1.webp?v=1779933696","url":"https:\/\/batteryweb.com\/products\/midea-i5-replacement-battery-148v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
