It fits the battery bay directly and connects to the robot's onboard BMS without modification. Capacity is rated at 75.5Wh, matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eScout RX2 120 and RX3 120 platform fit:\u003c\/strong\u003e\n    Both models share the same 14.52V power rail, battery bay dimensions, and BMS connector pinout — one cell covers both robots without adapter or wiring change.\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 an RX2 120 chassis. The BMS handshake completed on first dock contact, voltage held steady through the motor-start draw spike, and the cell balanced correctly across all discharge stages.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on the Scout RX series:\u003c\/strong\u003e\n    These robots return to the dock automatically and will trickle-charge indefinitely if left there. Remove the robot from the dock once the charge indicator shows full. Continuous dock contact accelerates capacity fade in Li-ion cells faster than periodic charge cycles do.\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 Scout RX2\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Scout RX2 120 drives its suction motor and navigation system from the same 14.52V bus. When the filter is partially blocked, the motor draws above its rated current to maintain airflow, pulling cell voltage down faster than normal discharge. The BMS reads this as a low-state condition and throttles output before the fuel gauge registers low. Clean or replace the filter first — if suction recovers immediately, the cell is not the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-cycle and then recovering after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a depleted battery. On restricted airflow — blocked brush roll, clogged filter, or debris jammed at the intake — the suction motor pulls a sustained current spike that exceeds the BMS trip threshold. The BMS cuts the output rail, the robot pauses, the current drops, and the BMS resets automatically. Clear the restriction at the brush roll and intake port, then verify the filter is seated correctly. If trips continue on an unblocked robot, check cell voltage at rest — it should read above 14.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428020551770,"sku":"BWCS-YCM720VX-1","price":60.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428020584538,"sku":"BWCS-YCM720VX-2","price":70.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428020617306,"sku":"BWCS-YCM720VX-3","price":78.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-YCM720VX-1.webp?v=1779933918","url":"https:\/\/batteryweb.com\/products\/miele-scout-rx2-120-replacement-battery-1452v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
