It slots directly into the RA 201 S battery compartment and restores power to the motor drive circuit. Use this when the original cell no longer holds a useful charge.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRA 201 S motor platform:\u003c\/strong\u003e\n    The RA 201 S runs a brushed DC motor on a 14.4V rail. Ni-MH chemistry matches the charge profile the onboard circuit expects. Dropping voltage or swapping chemistry disrupts that balance and can trip the protection circuit prematurely.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through repeated charge and discharge passes on the RA 201 S motor platform. The BMS held cutoff cleanly at end-of-discharge and accepted the full charge cycle without false trips.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging on the RA 201 S:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock continuously between uses. Ni-MH cells in cordless vacuums develop capacity fade noticeably faster under constant trickle charge. Charge to full, then remove 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\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the motor draws more current than the cell can deliver cleanly under load. A partially blocked filter is the most common trigger — restriction forces the motor to pull harder, which drags cell voltage down early. The BMS interprets this voltage sag as a depleted cell and begins throttling output. Clear the filter first, then retest under normal carpet load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean and then recovers after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When suction is sustained against a blockage or a heavily restricted filter, current draw spikes past the protection threshold and the BMS opens the circuit. After a brief cooldown the BMS resets and the motor runs again. Check the filter and clear any blockage at the inlet before running a full clean. If trips continue on a clean filter, measure resting cell voltage — it should sit above 12.5V after a full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428087496794,"sku":"BWCS-IRB400VX-1","price":82.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428087529562,"sku":"BWCS-IRB400VX-2","price":96.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428087562330,"sku":"BWCS-IRB400VX-3","price":107.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IRB400VX-1.webp?v=1779934037","url":"https:\/\/batteryweb.com\/products\/rolando-ra-201-s-replacement-battery-144v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
