It fits the RX receiver unit that pairs with the XP510 base station transmitter. Voltage and capacity match the original spec exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXP510 RX fit:\u003c\/strong\u003e\n    The XP510 system splits audio processing between the transmitter base and the RX headset unit. The RX unit runs its DECT radio and audio decoder from this single Li-Polymer cell — voltage must sit at 3.7V nominal or the DECT link drops before the audio stage shuts down.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell under combined DECT radio and audio draw. The BMS held the output rail steady across the full discharge curve and tripped cleanly at the low-voltage cutoff without dropping the wireless link mid-cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge in the base station:\u003c\/strong\u003e\n    Place the XP510 RX in its base station and run a complete charge cycle before use. The base station logs the new cell during this cycle — without it, the talk-time estimate on the headset will read inaccurate for the first several uses.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station not recognising the new pack after fitting\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe XP510 base uses a BMS handshake to confirm a valid cell is seated before it begins a charge cycle. A replacement cell ships at storage voltage — typically around 3.6V — which sits below the threshold the base expects for a fully initialised pack. If the base shows no charge indicator or flashes an error, the handshake has not completed. Seat the RX unit firmly in the cradle and leave it for a full charge cycle without interruption — this allows the BMS to complete initialisation and the base to register the cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHeadset cuts out mid-session even with battery showing charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe XP510 RX draws simultaneously from the DECT radio and the audio decoder — two loads that spike together during high-bandwidth audio moments. If the cell has aged or was stored for a long period, internal resistance rises and the combined draw causes a voltage sag that trips the BMS cutoff even when the indicated charge level looks healthy. This is not a firmware fault — it is the BMS protecting the cell. Fit a fresh cell and confirm the resting voltage reads at or above 3.7V before the first use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428104339546,"sku":"BWCS-HPX456SL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428104372314,"sku":"BWCS-HPX456SL-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428104405082,"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\/turtle-beach-xp510-rx-replacement-battery-37v-1500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
