It fits the Packtalk Edge directly, restoring power to the intercom, audio, and radio systems. Capacity matches the OEM spec at 700mAh (2.59Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePacktalk Edge fit:\u003c\/strong\u003e\n    The Packtalk Edge runs its DECT radio, Bluetooth audio, and DSP noise processing from a single 3.7V cell. This battery matches the OEM voltage rail and connector, and the BMS handshake completes normally on the Cardo charging dock without triggering a fault code.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the Packtalk Edge platform. The BMS accepted the pack without error, and the protection circuit responded correctly to both low-voltage cutoff and charge termination thresholds.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle dock requirement:\u003c\/strong\u003e\n    Seat the Packtalk Edge in its charging dock and run a complete charge before your first ride. The dock needs to log the new cell before the onboard firmware can report an accurate charge state — skipping this step causes the headset to show a full indicator that drops quickly under load.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Packtalk Edge cuts out mid-transmission on a fresh battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Packtalk Edge pulls its heaviest current when the DECT radio transmits and the DSP processes audio simultaneously. On a cell that hasn't completed its first conditioning cycle, internal resistance is still elevated — voltage sags under that combined draw and can trip the BMS protection circuit before the cell is genuinely depleted. The headset goes silent even though the charge indicator showed capacity remaining. Running three to five full charge and discharge cycles brings internal resistance down and closes the gap between indicated and usable charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharging dock shows full but headset shuts off after a short ride\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-Polymer cell ships at storage voltage — typically around 3.8V — not at full charge. The Packtalk Edge firmware reads that voltage as near-full and displays a misleading indicator before the first complete dock cycle runs. The fix is straightforward: place the headset in the dock, let it charge uninterrupted until the dock light confirms completion, then discharge fully on a test call before recharging. After that first full cycle, the charge reporting stabilises at the correct 4.2V fully charged reference.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428096409690,"sku":"BWCS-SRD140SL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428096442458,"sku":"BWCS-SRD140SL-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428096475226,"sku":"BWCS-SRD140SL-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SRD140SL-1.webp?v=1779934086","url":"https:\/\/batteryweb.com\/products\/cardo-packtalk-edge-replacement-battery-37v-700mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
