It replaces OEM part BP28825A when the original cell can no longer hold adequate charge. Fits both the handheld and upright configurations of these models.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eP7 and Q8 platform compatibility:\u003c\/strong\u003e\n    Both models run the same 29.6V battery rail and share the BP28825A connector and BMS handshake. The same cell pack works across the P7 and Q8 without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on the P7 platform under simulated carpet load. The BMS held voltage through sustained high-draw cycles and tripped correctly on overcurrent — no false shutdowns on normal operation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit for this vacuum:\u003c\/strong\u003e\n    Do not leave the P7 or Q8 sitting on the charging dock permanently. Continuous trickle charging degrades cell capacity faster than almost any other use pattern. 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\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a motor voltage sag issue, not a capacity issue. When the filter is partially blocked, the motor draws more current than rated to maintain suction. That extra draw pulls cell voltage down under load, so the vacuum loses power even though the indicator still shows charge remaining. Clean or replace the filter first — if suction recovers and holds, the battery is fine. If sag continues on a clean filter, the cell pack has degraded below the threshold where it can sustain the motor's peak draw.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-use then recovers after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip caused by sustained restricted airflow, not a faulty battery. When suction is blocked — a clogged filter, a jammed brush roll, or a sealed nozzle — the motor stalls briefly and current spikes above the BMS protection threshold. The BMS cuts power, the motor cools, and the BMS resets. Check the brush roll for hair or debris wrapping and clean the filter before assuming the battery is at fault. If the cutout stops after clearing the blockage, the cell is working correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427991060570,"sku":"BWCS-ERH110VX-1","price":84.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427991093338,"sku":"BWCS-ERH110VX-2","price":98.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427991126106,"sku":"BWCS-ERH110VX-3","price":109.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ERH110VX-1.webp?v=1779933799","url":"https:\/\/batteryweb.com\/products\/media-p7-replacement-battery-296v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
