It matches the OEM part number SPCC1B and fits the ACBAT-001 form factor. The cell slides into the same battery bay and connects via the same contact plate as the original.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMax and Max 360 platform fit:\u003c\/strong\u003e\n    Both cameras share the same battery bay dimensions, contact layout, and BMS handshake protocol — that's why one cell covers the full Max line. The SPCC1B spec was carried across both variants without revision.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the GoPro Max's charge and discharge cycle on the bench. The BMS accepted the cell, reported charge state without error, and thermal behaviour stayed within normal bounds across full 360-degree recording load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003e360 recording draw tip:\u003c\/strong\u003e\n    The Max runs two lenses simultaneously during 360 capture. That dual-sensor load pulls more current than a standard single-lens action camera. Avoid switching between 360 and HERO mode repeatedly in a single session — each mode switch triggers a brief high-current spike that accelerates cell wear faster than sustained recording at one setting.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the GoPro Max shows a dead battery icon on a new replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe GoPro Max uses a fuel-gauge IC that maps voltage thresholds to percentage remaining. A new cell shipped at storage charge — typically around 3.6V to 3.7V — can sit below the camera's \"battery present and healthy\" threshold if the IC hasn't been initialised with that cell. The camera reads the resting voltage, mismatches it against a partially discharged profile, and throws a dead or near-empty indicator. Running one full charge cycle through the OEM charger or directly via USB-C into the camera body resets the fuel gauge and aligns it to the new cell's discharge curve. After that cycle, the indicator reads accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping or dropping suddenly during recording\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camera's voltage-to-percentage lookup table doesn't yet match the discharge curve of the replacement cell. The GoPro Max samples cell voltage under load — 360 recording draws a variable current depending on bitrate and stabilisation — and maps that reading to a percentage. If the curve mapping is off, a voltage sag during a high-draw moment reads as a steep percentage drop, then recovers when current demand eases. One full charge-discharge cycle through the camera body recalibrates the relationship between voltage and displayed percentage. After that cycle, the readout stabilises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333621022810,"sku":"BWCS-GDB810MC-1","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333621055578,"sku":"BWCS-GDB810MC-2","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333621088346,"sku":"BWCS-GDB810MC-3","price":38.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GDB810MC_1.webp?v=1778212976","url":"https:\/\/batteryweb.com\/products\/gopro-max-replacement-battery-385v-1400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
