It fits the RED One, Epic, and Scarlet Dragon cinema camera systems. These are demanding 4K production platforms that pull hard on battery during sustained recording, so having a confirmed replacement cell matters.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRED One, Epic, and Scarlet Dragon compatibility:\u003c\/strong\u003e\n    All three platforms share the same 14.8V battery rail and use the same physical connector and BMS communication protocol. A cell validated on one will seat and communicate correctly on the others. The Dragon sensor variant draws more current during sustained 6K recording — keep that in mind when managing power on set.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the RED power system and confirmed BMS handshake, accurate state-of-charge reporting, and stable voltage delivery under high-throughput recording load. No dropout events were recorded during sustained camera operation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on RED cameras:\u003c\/strong\u003e\n    Slot the battery into the camera body and run one full charge cycle through the camera or OEM RED charger before your first shoot. Some RED BMS firmware requires this initial cycle to calibrate the percentage display correctly. Skipping it can cause the indicator to jump or read inaccurately from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the RED One battery percentage drops suddenly during high-bitrate recording\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe RED One pulls significantly more current when recording at peak bitrates — sensor readout, image processor, media module, and fan all draw simultaneously. A replacement cell with a slightly different internal resistance profile can trigger the BMS to report a steep voltage drop under that combined load, even if the cell has capacity remaining. This shows as a sudden percentage jump downward. It is not a fault with the cell — it is the BMS reading instantaneous voltage under surge draw rather than rested voltage. Let the camera idle briefly and the displayed percentage will recover.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRED camera body showing \"no battery\" or refusing to power on with a new cell installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the BMS authentication handshake fails on first install. The RED camera expects a specific charge state acknowledgment from the cell before it will power the system. If the replacement cell arrives partially discharged, the camera may reject it entirely rather than attempt to run on low voltage. Insert the battery and connect the camera to a RED-compatible charger first — charge it to at least 12.5V resting voltage before trying to power the body. One full charge cycle through the camera body resolves this in the majority of cases.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333637374042,"sku":"BWCS-SBP470MC-1","price":152.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333637406810,"sku":"BWCS-SBP470MC-2","price":176.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333637439578,"sku":"BWCS-SBP470MC-3","price":194.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SBP470MC-1.webp?v=1778212994","url":"https:\/\/batteryweb.com\/products\/red-one-replacement-battery-148v-3200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
