It fits the dual-lens body directly and uses the same connector and BMS handshake as the original. Capacity is 6.55Wh — matching the stock specification from the product data.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOne X2 compatibility:\u003c\/strong\u003e\n    The One X2 uses a specific 3.85V cell with a multi-pin connector that carries both power and BMS communication. This battery matches that connector pinout and voltage rail, so the camera body recognises it on insertion without firmware prompts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the One X2 charge cycle using an OEM-spec charger. The BMS accepted the cell, reported charge state accurately after one full cycle, and held voltage within the expected discharge curve under continuous 360 recording load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle initialisation on the One X2:\u003c\/strong\u003e\n    Charge this battery fully inside the camera body before your first shooting session. The One X2 BMS maps its battery-remaining display to the cell's discharge curve during that first charge — skipping it can cause the indicator to read 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\"\u003eWhy the One X2 battery percentage jumps erratically after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe One X2 uses a voltage-threshold model to estimate remaining charge. A new cell has a slightly different discharge curve than a broken-in OEM cell, so the camera's threshold mapping can read the wrong percentage until the BMS recalibrates. This shows up as the indicator jumping from, say, 60% to 20% without any heavy use in between. Run one full charge-to-discharge cycle — charge to 100% in the camera, then record until the camera shuts off automatically — and the indicator will stabilise. After that cycle, percentage reporting aligns with the new cell's actual curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eOne X2 showing a dead battery icon with a cell that charged overnight\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when a replacement cell is charged externally before the camera's BMS has authenticated it. The One X2 BMS runs an initialisation check on first contact with the camera body — if it hasn't completed that check, the camera can reject the cell entirely and display a dead or missing battery icon. Remove the battery, reinsert it, and charge it from 0% directly inside the camera body using a USB-C cable rated at least 18W. Once the camera reaches 100% through that in-body charge, the BMS registers the cell as valid and the icon clears.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333613224026,"sku":"BWCS-NTX362MC-1","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333613256794,"sku":"BWCS-NTX362MC-2","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333613289562,"sku":"BWCS-NTX362MC-3","price":38.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NTX362MC-1.webp?v=1778212994","url":"https:\/\/batteryweb.com\/products\/insta360-one-x2-replacement-battery-385v-1700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
