It powers the three-axis brushless motor assembly that keeps your camera steady during filming. Voltage and capacity match the OEM specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eThree-axis motor platform:\u003c\/strong\u003e\n    The gimbal's pitch, roll, and yaw motors each draw current simultaneously during active stabilisation. All three share this single cell, so the BMS must handle combined peak loads — especially during fast pans or aggressive directional changes. This battery's BMS threshold matches that combined draw profile.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through startup initialisation and sustained 3-axis stabilisation cycles. The BMS held stable under simultaneous motor draw without tripping, and voltage output stayed consistent through full discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBalance before powering on:\u003c\/strong\u003e\n    Balance the gimbal with your camera attached before switching on. An unbalanced load forces all three motors to work harder continuously — that constant overcorrection draws significantly more current than normal operation and puts unnecessary stress on the BMS during peak moves.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGimbal not initialising correctly after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe IMU calibration sequence at startup requires a stable, consistent voltage supply during the first few seconds of power-on. A battery with a weak or unresponsive BMS can deliver an inconsistent voltage spike or dip right at that moment, causing the gimbal to misread sensor data or fail the self-check entirely. If the gimbal twitches, locks up, or throws a calibration error after a battery swap, the fix is simple — power off fully, wait ten seconds, then power back on with the gimbal sitting flat and still on a level surface. That gives the IMU a clean, stable read at 3.7V nominal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eStabilisation drifting or softening before the battery indicator shows low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe battery indicator reads cell voltage, not available motor current. As the cell ages or cools down, internal resistance climbs — voltage sags under the simultaneous draw of all three motors even while the display still shows two or three bars. The motors receive less voltage than the controller expects, so correction torque drops and footage looks like the stabilisation is losing its grip. Check actual resting cell voltage with a multimeter at the charge port; anything below 3.5V under light load means the cell can no longer sustain motor-start current peaks and the battery needs replacing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377553178714,"sku":"BWCS-NTA692MC-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377553211482,"sku":"BWCS-NTA692MC-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377553244250,"sku":"BWCS-NTA692MC-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NTA692MC-1.webp?v=1778771653","url":"https:\/\/batteryweb.com\/products\/insta360-replacement-battery-37v-2900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
