It slots into the same battery bay as the original cell and connects to the same BMS communication circuit. No OEM part number is published for this cell — the Duoro and Duoro Profi share identical battery architecture.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDuoro and Duoro Profi compatibility:\u003c\/strong\u003e\n    Both models run the same 14.4V motor rail and use the same battery housing and connector pinout. One cell fits both without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge cycles and monitored BMS behaviour under sustained motor load. The protection circuit held cutoff voltage correctly and did not trip under normal suction cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging on cordless vacuums:\u003c\/strong\u003e\n    Do not leave the Duoro sitting on its charging dock continuously. Unlike a phone, this vacuum has no dock-detection circuit to pause trickle charge once full. Charge to full, then remove it 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 Duoro\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Duoro's motor draws significantly more current when the filter is partially blocked — sometimes two to three times its clean-filter draw. That elevated current causes voltage to sag at the cell before the indicator circuit registers a low-battery state. The result is reduced suction with the indicator still showing partial charge. Clean the filter first. If sag continues on a clean filter, the cell has lost capacity and needs replacing.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-clean and recovering after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a power switch fault. When suction is restricted — blocked filter, tangled brush roll, or a sealed floor contact — motor current spikes beyond the BMS threshold and the protection circuit cuts output. The cell recovers once current drops below the trip point, which is why the vacuum restarts after a brief pause. Clear the blockage and check the filter. If trips continue on an unblocked machine, measure resting cell voltage — a cell below 14.0V at rest has deteriorated and will trip under normal load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426482323546,"sku":"BWCS-RBD100VX-1","price":305.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426482356314,"sku":"BWCS-RBD100VX-2","price":365.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426482389082,"sku":"BWCS-RBD100VX-3","price":410.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RBD100VX-1.webp?v=1779933440","url":"https:\/\/batteryweb.com\/products\/robzone-duoro-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
