It fits the compact battery bay on CHDHX-501 and ASST1 bodies, along with ten additional Hero-series models. Dimensions are 35.80 × 31.20 × 11.30mm — same footprint as the OEM AHDBT-501.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHero 5 and Hero 6 platform fit:\u003c\/strong\u003e\n    Both cameras share the same battery bay dimensions, connector pinout, and BMS communication protocol. One cell covers both bodies without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the Hero 5 body. The BMS accepted the cell, voltage at full charge read 4.35V, and the camera reported battery level correctly through a full discharge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle on Hero 5:\u003c\/strong\u003e\n    Insert the new cell and charge it directly inside the camera body before your first shoot. The Hero 5 BMS maps its battery-remaining display against a full internal charge cycle — skipping this step can cause the indicator to read inaccurately until one complete cycle is completed in-body.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Hero 5 battery percentage jumps erratically with a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Hero 5 uses a voltage-threshold model to estimate remaining capacity. A new cell has a slightly different discharge curve shape than an aged OEM cell, so the camera's thresholds don't align correctly on the first cycle. The indicator may jump from 80% to 40% without warning, or hold at 100% longer than expected. After one or two full charge-and-discharge cycles completed inside the camera body, the display stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHero 5 showing dead battery icon on a cell you know has charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops below the camera's minimum wake threshold — typically around 3.0V — usually from storage in a discharged state. The BMS locks out the cell as a protection measure and the body won't power on. Place the cell in an external USB charger set to Li-ion 3.85V mode for 15–20 minutes to recover it to at least 3.2V, then reinsert it into the camera body to resume normal charging.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333672173658,"sku":"BWCS-GDB501MX-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333672206426,"sku":"BWCS-GDB501MX-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333672239194,"sku":"BWCS-GDB501MX-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GDB501MX-1.webp?v=1778213016","url":"https:\/\/batteryweb.com\/products\/gopro-hero-5-replacement-battery-385v-1250mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
