It replaces OEM part CINAQBT\/A and uses the same connector and physical footprint as the original. Voltage and capacity match the One X3's power system exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOne X3 power system fit:\u003c\/strong\u003e\n    The One X3 uses a single-cell 3.85V pack with a multi-pin connector that carries both power and BMS communication data. This cell matches that pin layout and voltage rail, so the camera's battery management system can read state-of-charge correctly without a handshake error.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the One X3 body. The BMS accepted the cell without a rejection flag, and the protection circuit tripped correctly at the low-voltage cutoff threshold — no hard shutdowns mid-cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003e360-degree sensor load tip:\u003c\/strong\u003e\n    The One X3 runs two wide-angle lenses and dual image sensors simultaneously. Avoid pulling the battery mid-session without powering the camera down first — abrupt cuts under full sensor load can cause the BMS to log a fault state that affects charge-remaining accuracy on the next cycle.\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 X3 shows a dead-battery indicator on a freshly installed replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe One X3's fuel gauge maps battery percentage to a specific discharge curve stored in the camera firmware. A new third-party cell arrives at a partial state of charge, and the camera may read that mid-range voltage as critically low if it hasn't calibrated to the new cell yet. This triggers the dead-battery icon even though the cell has usable charge remaining. Run one full charge cycle through the camera body or OEM charger — this gives the BMS enough data points to remap its percentage readout to the new cell's actual curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically during recording on the One X3\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camera's voltage-threshold indicator interprets the new cell's discharge curve differently from the original cell it was calibrated against. The One X3 pulls higher instantaneous current during 360-degree video encode, which causes brief voltage sag — the BMS reads that dip and recalculates percentage sharply downward, then recovers. It is a calibration mismatch, not a faulty cell. Complete two full charge-to-discharge cycles in the camera body and the percentage display will stabilise as the BMS builds an accurate model of the new cell — verify by charging to 4.20V before the second cycle begins.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333583405146,"sku":"BWCS-NTX363MC-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333583437914,"sku":"BWCS-NTX363MC-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333583470682,"sku":"BWCS-NTX363MC-3","price":40.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NTX363MC-1.webp?v=1778212994","url":"https:\/\/batteryweb.com\/products\/insta360-one-x3-replacement-battery-385v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
