It carries a 6800mAh capacity and matches the OEM part number 4228 00100. The battery fits directly into the Navaggio Profi's battery compartment and communicates with the onboard BMS as the original unit does.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eETA 4228 Navaggio Profi fit:\u003c\/strong\u003e\n    The Navaggio Profi uses a 14.4V Li-ion pack with a specific BMS handshake tied to part number 4228 00100. This replacement matches that voltage rail, connector pinout, and BMS communication so the vacuum recognises the pack and allows charging and discharge as normal.\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 the Navaggio Profi platform. The BMS accepted the cell, the charge indicator behaved correctly, and the vacuum reached full operating suction without triggering overcurrent cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging on the Navaggio Profi:\u003c\/strong\u003e\n    Do not leave the Navaggio Profi sitting on its charging dock between uses. Continuous dock contact delivers a trickle charge that accelerates capacity fade in Li-ion cells. Charge to full, then remove the unit from the dock until the next use.\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 on the Navaggio Profi\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Navaggio Profi's motor draws significantly more current when the filter is partially blocked or the suction path is restricted. Under that extra load, voltage sags at the pack terminals before the fuel gauge registers a low-battery event. The BMS reads the voltage drop as a protection condition and throttles output to the motor. Clean the filter and check for blockages first — if suction restores immediately, the battery is not the cause.\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's suction path is restricted — typically a clogged filter or blocked nozzle — the motor spins harder and pulls current beyond the BMS trip threshold. The BMS cuts power to protect the cells, then resets after a brief cooldown. Clear the filter and nozzle, then restart the vacuum; if the cutout stops, the pack is functioning correctly and the fault was airflow restriction, not the battery.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426392834138,"sku":"BWCS-ETN423VX-1","price":105.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426392866906,"sku":"BWCS-ETN423VX-2","price":124.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426392899674,"sku":"BWCS-ETN423VX-3","price":138.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ETN423VX-1.webp?v=1779931232","url":"https:\/\/batteryweb.com\/products\/eta-4228-navaggio-profi-replacement-battery-144v-6800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
