It fits the RED One, Epic, and Scarlet Dragon cinema cameras. Voltage and capacity match the OEM spec for these bodies.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOne, Epic, and Scarlet Dragon compatibility:\u003c\/strong\u003e\n    All three platforms share the same battery bay format, 14.8V nominal rail, and connector pinout. The SM-4230RC spec covers the BMS communication handshake common across this RED camera line, so the same cell works across all three 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 charge and discharge cycles on a RED-compatible body and logged BMS handshake acknowledgement on first install. The protection circuit responded correctly to charge termination and low-voltage cutoff without tripping prematurely under the camera's sustained 4K sensor and recording load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle on RED bodies:\u003c\/strong\u003e\n    Charge this battery fully via the OEM RED charger or directly in the camera body before your first shoot. Some RED bodies require a complete charge cycle from within the camera to calibrate the battery-remaining display — skipping this step can cause the indicator to read inaccurately from the first use.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy RED cinema cameras run a BMS authentication check on new cells\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRED camera bodies query the battery's BMS over the communication pins before displaying charge state or allowing full operation. A new third-party cell may not pass this check on the very first power-on if the BMS hasn't completed an initial charge handshake. This is a one-time initialisation step, not a fault. Charge the cell to 100% in the OEM RED charger, then re-insert — the body will recognise it and report charge state correctly from that point forward.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the RED body display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRED bodies map the battery percentage indicator against a voltage-threshold curve calibrated to the OEM cell's discharge profile. A replacement cell with a slightly different discharge curve can cause the display to jump — for example, reading 80% then dropping to 55% within a short period without heavy use. This isn't a capacity fault; it's the indicator mapping voltage readings differently to the new cell. Run one full discharge-to-cutoff cycle followed by a full charge, and the body's BMS will recalibrate its threshold mapping to the replacement cell's actual curve. Target a full charge to 16.8V before returning to use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333639110746,"sku":"BWCS-SBP950MC-1","price":164.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333639143514,"sku":"BWCS-SBP950MC-2","price":190.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333639176282,"sku":"BWCS-SBP950MC-3","price":209.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SBP950MC-1.webp?v=1778213032","url":"https:\/\/batteryweb.com\/products\/red-one-replacement-battery-148v-6400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
