It replaces original packs that have lost capacity or no longer hold a usable charge. Swap takes under a minute — no tools needed.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eX-One, RJD3A, Duel 3, and Focus compatibility:\u003c\/strong\u003e\n    These models share the same 14.4V battery platform, connector format, and BMS handshake protocol. One pack fits the full range 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 and discharge cycles on an X-One unit. The BMS registered cell voltage correctly, accepted charge without error codes, and held steady voltage output under the motor's normal operating load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on the X-One:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock continuously between uses. The X-One dock does not cut charge current once the pack reaches full — prolonged dock time causes trickle-charge stress that degrades cell capacity faster than normal cycling. Charge to full, then remove it.\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\"\u003eThe X-One's motor draws significantly more current when airflow is restricted — a partially blocked filter can push draw well above normal operating levels. The BMS detects the voltage sag and pulls back output to protect the cells, which the motor reads as low power. The suction feels weak even though the indicator still shows charge. Clean or replace the filter first — if suction restores immediately, the battery was never the problem.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean then recovers after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When the motor sustains a high-draw state — usually from a blocked filter or sustained contact with thick carpet — the BMS cuts output to prevent cell damage, then resets after a brief cooldown. It will keep repeating until the restriction is cleared. Check the filter and the intake path, then verify the resting pack voltage sits above 12.5V before concluding the battery is faulty.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426414919770,"sku":"BWCS-BPK130VX-1","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426414952538,"sku":"BWCS-BPK130VX-2","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426414985306,"sku":"BWCS-BPK130VX-3","price":59.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BPK130VX-1.webp?v=1779933520","url":"https:\/\/batteryweb.com\/products\/robojet-x-one-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
