It fits the RED One, Epic, and Scarlet Dragon cinema cameras. Voltage and cell chemistry match the original pack — the camera's power rail and BMS receive what they expect.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOne, Epic, and Scarlet Dragon platform fit:\u003c\/strong\u003e\n    All three bodies use the same V-lock adjacent battery interface, 14.8V nominal rail, and share the SM-4230RC specification. The connector keying and BMS handshake protocol are identical across the platform, so one replacement pack covers all three bodies.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on compatible RED hardware. The BMS reported accurate state-of-charge and engaged protection cutoffs at expected low-voltage thresholds. No false-low warnings appeared during mid-cycle draws.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle on RED bodies:\u003c\/strong\u003e\n    Seat the battery and run a full charge through the OEM charger or camera body before your first shoot. RED's BMS maps the discharge curve during this initial cycle — skipping it can cause the battery-remaining indicator to read inaccurately throughout the pack's life.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy RED One and Epic bodies reject a new third-party cell on first install\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eRED cinema bodies perform an authentication check against the battery's BMS on every power-on. A fresh cell that has not yet completed a charge cycle from within an approved charger can fail this handshake and trigger a \"no battery\" or \"incompatible\" flag. The body is reading an uncalibrated state-of-charge register, not a hardware mismatch. One full charge via the RED charger or camera body resolves this — the BMS writes the calibration data the camera needs to accept the pack.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically during a RED Dragon shoot\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe RED battery indicator maps display percentage to specific voltage thresholds calibrated for the OEM cell's discharge curve. A replacement cell with a slightly different mid-range discharge slope causes the indicator to jump — for example, dropping from 60% to 30% within a few minutes of heavy sensor and codec load. The cell is not defective; the voltage is falling through thresholds the camera treats as steep drop-off points. Run two full charge-discharge cycles through the camera body and the BMS will remap its threshold readings to the actual discharge curve of the new pack.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333638651994,"sku":"BWCS-SBP142MC-1","price":224.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333638684762,"sku":"BWCS-SBP142MC-2","price":262.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333638717530,"sku":"BWCS-SBP142MC-3","price":291.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SBP142MC-1.webp?v=1778213032","url":"https:\/\/batteryweb.com\/products\/red-one-replacement-battery-148v-9600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
