It fits the GY-HMQ10, GY-HM600E, GY-HM600EC, GY-HMQ10E, and related models in that lineup. The cell matches OEM voltage, capacity, and connector pinout for the SSL-JVC50 slot.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGY-HM600 and GY-HMQ10 platform fit:\u003c\/strong\u003e\n    These models share the same SSL-JVC50 battery bay, 7.4V nominal voltage rail, and multi-pin communication interface. The BMS handshake expects a specific cell voltage signature at startup — this replacement meets that requirement.\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 GY-HM600E platform. The BMS accepted the cell on first install, reported charge status correctly, and held voltage within 0.1V of OEM across the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on GY-series bodies:\u003c\/strong\u003e\n    Insert the cell into the camera body and run a full charge via the OEM charger before your first shoot. JVC's battery management system maps the remaining-charge display to a discharge curve it calibrates on that first cycle — skipping it can cause the indicator to read inaccurately for the first few uses.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the GY-HMQ10 reports an unexpected low-battery warning during 4K recording\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe GY-HMQ10 runs four simultaneous codec streams during 4K recording, which pulls significantly more current than single-stream HD modes. That extra draw causes a sharper voltage sag mid-cell, which the camera's BMS can read as a low-battery condition even when the cell is not depleted. A replacement cell with a fresh, unaged anode handles that transient sag better than a degraded original. If the warning appears repeatedly, check that the battery contacts on the camera body are clean — even slight oxidation raises contact resistance and worsens the sag.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the GY-HM600E display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camera's fuel-gauge algorithm is still mapped to the discharge curve of the old, degraded cell. A new cell has a flatter mid-range voltage curve than a worn one, so the indicator can skip or jump until the BMS recalibrates. Run one complete charge-to-full, then discharge-to-cutoff cycle inside the camera body — do not pull the cell partway through. After that single calibration cycle, the percentage display should stabilise and track the new cell accurately down to the 3.0V per-cell cutoff.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333701271642,"sku":"BWCS-JHM600MX-1","price":52.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333701304410,"sku":"BWCS-JHM600MX-2","price":61.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333701337178,"sku":"BWCS-JHM600MX-3","price":68.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-JHM600MX_1.webp?v=1778213017","url":"https:\/\/batteryweb.com\/products\/jvc-gy-hmq10-replacement-battery-74v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
