It fits the One X4 body directly and is sized to the original 63.40 × 43.30 × 15.50mm form factor. Voltage and capacity match the stock cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOne X4 platform fit:\u003c\/strong\u003e\n    The One X4 runs a BMS that checks cell voltage on insertion. This replacement matches the 3.85V nominal rail the camera expects, so the handshake completes without throwing a rejection error on boot.\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 One X4 body. The BMS logged charge termination at the correct cutoff voltage and reported cell status without flagging a fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge cycle on the One X4:\u003c\/strong\u003e\n    Run the first full charge through the camera body using the OEM cable, not a third-party dock. Some One X4 units need one in-body charge cycle before the battery-remaining display calibrates accurately to a new cell's discharge curve.\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 X4 shows a dead battery indicator on a replacement cell that isn't empty\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe One X4 maps its battery percentage to a voltage-threshold table built around the OEM cell's discharge curve. A new third-party cell can sit at 3.70V and read as critically low because the camera expects a different curve shape at that voltage point. This is a calibration mismatch, not a faulty cell. One full charge-discharge cycle inside the camera body re-maps the indicator to the actual discharge profile of the new cell. After that cycle, the percentage display tracks correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically during 360 video recording\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSustained 360 recording stacks sensor readout, gyroscope stabilisation, and dual-lens stitching processing all at once — that combined draw pulls voltage down faster than the indicator samples it, so the display skips steps rather than stepping down smoothly. This is not cell failure; it is the indicator losing pace with a high and variable load. If the jumps occur only during active recording and the cell recovers to a stable reading when the camera is idle, the cell is functioning correctly. Confirm the cell rests above 3.60V at idle after a recording session to rule out an actual low-capacity fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333571772506,"sku":"BWCS-NTX364MC-1","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333571805274,"sku":"BWCS-NTX364MC-2","price":56.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333571838042,"sku":"BWCS-NTX364MC-3","price":62.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NTX364MC-1.webp?v=1778212955","url":"https:\/\/batteryweb.com\/products\/insta360-one-x4-replacement-battery-385v-2350mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
