It matches the OEM voltage rail and BMS handshake the vacuum's motor controller expects. Cross-references cover part numbers UR1860ZT-4S1P-AAF, 18650B4-4S1P-AAF4, and EBVB-266.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVR2000 2v1 compatibility:\u003c\/strong\u003e\n    The VR2000 platform runs a 4S1P 18650 cell configuration at 14.8V nominal. The motor controller uses a BMS handshake to verify cell chemistry before enabling full power. This pack matches that configuration exactly — incorrect voltage triggers a hard cutoff on startup.\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 VR2000 platform. The BMS balanced cells correctly across all four series positions, and the motor controller accepted full power mode without fault codes on every test cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging discipline for the VR2000:\u003c\/strong\u003e\n    The VR2000 charging dock delivers a continuous trickle once the battery reaches full charge. Leaving the vacuum docked permanently accelerates capacity fade in Li-ion 4S packs faster than occasional full-discharge cycles do. Charge to full, then pull it off 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 happens when the motor draws more current than the BMS current threshold allows under load — not because the cells are depleted. On the VR2000, a partially blocked filter forces the motor to work harder, pulling sustained current above what the 2600mAh pack's BMS is rated to supply continuously. The BMS doesn't cut out completely; it throttles output voltage, which the motor controller reads as low battery and reduces suction. Clean or replace the filter first, then retest — a clear airway drops motor draw back within the BMS's continuous current rating.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out and recovering mid-clean on carpet\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a failed battery. Thick carpet and rug edges create sudden suction restriction — the motor spikes current to compensate, crosses the BMS overcurrent threshold, and the pack disconnects for one to three seconds before resetting. It recovers because the BMS is doing exactly what it's supposed to. Check the filter and brush roll for blockage; both increase restriction. If the cutouts continue on clear flooring with a clean filter, measure pack voltage at rest — it should read above 15.8V on a full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428002791514,"sku":"BWCS-ZCA400VX-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428002824282,"sku":"BWCS-ZCA400VX-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428002857050,"sku":"BWCS-ZCA400VX-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZCA400VX-1.webp?v=1779933756","url":"https:\/\/batteryweb.com\/products\/concept-vr2000-2v1-perfect-clean-replacement-battery-148v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
