The LS35X runs wireless audio and its transmitter circuit from this single cell. When the original cell degrades and charge no longer holds, this replacement restores full function without replacing the headset.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLS35X platform fit:\u003c\/strong\u003e\n    The LS35X uses a compact Li-Polymer cell to power both the wireless radio and audio amplifier from the same voltage rail. The cell dimensions — 50.70 × 34.00 × 8.00mm — match the original pack envelope, and the connector orientation aligns with the board without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell under combined wireless and audio draw. The BMS held voltage stable through sustained use and triggered cutoff cleanly at low charge rather than dropping unexpectedly mid-session.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on the LS35X:\u003c\/strong\u003e\n    Seat the headset in its base station and run a full charge cycle before use. The base station logs the new cell during this cycle — without it, the talk-time indicator reads inaccurately for the first several sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing a charging error after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe LS35X base station communicates with the headset's BMS to confirm cell status before registering a charge cycle. If the new cell arrives at storage voltage — typically around 3.6V — the base may flag an error or show no charge activity at all. This is a BMS handshake issue, not a fault with the battery or the base. Place the headset in the cradle and leave it undisturbed for a full charge cycle; the handshake completes once the BMS reports a valid state-of-charge above the base's recognition threshold.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHeadset cutting out mid-session on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe LS35X draws from the cell simultaneously for the wireless transmitter and the audio amplifier. Under that combined load, a cell not yet through its first conditioning cycles can sag below the BMS cutoff threshold — triggering a shutdown that looks like a flat battery. This is not a defective cell. Run three to five full charge and discharge cycles through the base station, and the voltage floor under load stabilises. After conditioning, cutoffs under normal use should occur at or below 3.2V rather than mid-session.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428104142938,"sku":"BWCS-HPX456SL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428104175706,"sku":"BWCS-HPX456SL-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428104208474,"sku":"BWCS-HPX456SL-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPX456SL-1.webp?v=1779934117","url":"https:\/\/batteryweb.com\/products\/lucidsound-ls35x-replacement-battery-37v-1500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
