It fits directly into the One X body and matches the OEM cell dimensions at 38.23 × 31.80 × 9.85mm. Voltage and capacity figures match the original PL903135VT specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOne X platform fit:\u003c\/strong\u003e\n    The One X uses a single cell with a fixed 3.8V nominal rail and a specific contact layout on the battery door. This cell replicates that contact spacing and BMS communication path so the camera body accepts it without a firmware conflict.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell in an Insta360 One X body and confirmed the BMS handshake completed on first install. Charge acceptance, temperature monitoring, and discharge cutoff all triggered at expected thresholds during a full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle conditioning on the One X:\u003c\/strong\u003e\n    Run one complete charge cycle through the camera body or the OEM USB-C charger before heavy shooting. The One X BMS maps its battery-remaining display to a discharge curve it calibrates on first use — skipping this step causes the indicator to read inaccurately from the start.\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 X battery percentage jumps erratically after installing a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe One X battery indicator is mapped to a voltage-threshold table calibrated against the original cell's discharge curve. A new cell, even at the correct capacity, discharges through those voltage steps at a slightly different rate until the BMS has logged a full cycle. This causes the display to skip or jump — often dropping sharply from 80% to 30% mid-use. One full charge-to-discharge cycle corrects the calibration and stabilises the readout.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eOne X shows dead battery icon on a replacement cell that still has charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage has dropped below the camera's low-battery cutoff threshold — typically around 3.2V — but the cell itself has not fully discharged. It can also occur if the replacement cell shipped at a low storage charge. Connect the battery to the OEM charger via USB-C and let it charge uninterrupted until the indicator shows full. If the camera still shows a dead battery icon after a complete charge cycle, check the contacts on the battery door for debris or a bent pin — a poor contact causes the camera to read an artificially low voltage at the input rail.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333640683610,"sku":"BWCS-NTX360MC-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333640716378,"sku":"BWCS-NTX360MC-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333640749146,"sku":"BWCS-NTX360MC-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NTX360MC-1.webp?v=1778213032","url":"https:\/\/batteryweb.com\/products\/insta360-one-x-replacement-battery-38v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
