When the original cell degrades after repeated charge cycles, audio drops and intercom range suffers. This replacement restores full operation to the headset unit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eQ2 and Multiset Q2 platform fit:\u003c\/strong\u003e\n    These models share the same cell footprint, connector pinout, and BMS handshake protocol — the 49.00 × 20.10 × 4.70mm form factor seats correctly in all units on this platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the Q2's charge controller and confirmed the BMS completed its handshake without error, held charge correctly, and delivered stable voltage under the combined Bluetooth radio and audio draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle base station charge:\u003c\/strong\u003e\n    Seat the headset in the base station and run one complete charge cycle before making a call. The base logs the new cell during this cycle — without it, the talk-time estimate displayed will be inaccurate and the headset may cut off earlier than expected.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Q2 cuts out mid-transmission on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Q2 draws on two loads at once — the Bluetooth radio and the audio amplifier. Under combined draw, a cell at storage voltage can sag below the BMS cutoff threshold before completing a full transmission. This is not a faulty cell. It means the battery has not yet completed its first full charge cycle in the base station and the BMS has not yet calibrated to the new cell. One full base-station charge cycle resolves this.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than rated for the first few rides\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells do not reach full capacity on the first charge. On a fresh replacement, expect noticeably shorter talk time for the first three to five cycles — this is normal electrochemical conditioning, not a defect. Each full charge-discharge cycle allows the cell's active material to fully utilise its capacity. By cycle five, talk time should be at or near the rated figure.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428147593306,"sku":"BWCS-SRD200SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428147626074,"sku":"BWCS-SRD200SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428147658842,"sku":"BWCS-SRD200SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SRD200SL-1.webp?v=1779934245","url":"https:\/\/batteryweb.com\/products\/scala-rider-scala-rider-q2-replacement-battery-37v-400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
