{"product_id":"rebelcell-convertisseur-dc-dc-12v25a-ip65","title":"Waterproof DC-DC converter 12.4 V 25 A","description":"\u003cp\u003eThe \u003cstrong\u003eRebelcell DC-DC converter 12V25A\u003c\/strong\u003e converts an input DC voltage between 8 and 42 V into a stabilized 12.4 V output, limited to 25 A \/ 310 W. It allows designing a power supply for 12 V electronics on a compatible battery, notably a fishfinder with a depth sounder. It does not charge a battery and does not validate any specific device, engine or installation.\u003c\/p\u003e\u003cp\u003eInput and output use M4 terminals. The manufacturer provides for external 25 A fuses on both sides and includes two additional 25 A fuses with M4 connectors in the kit; connection cables are not included. The converter has \u003cstrong\u003eno reverse polarity protection\u003c\/strong\u003e: check polarity, actual voltage, total current, connectors, cable cross-section and length before connection. No specific fishfinder or universal harness is included.\u003c\/p\u003e\u003cp\u003eThe housing is rated IP65, but Rebelcell recommends a dry, cool, ventilated location, never at the bottom of the boat or on the battery. It must not be submerged. Net weight 1.45 kg; dimensions 150 × 130 × 50 mm. The manufacturer’s page refers to installation instructions without providing a downloadable PDF manual as of September 30, 2026. The professional portal listed this reference in stock; Skysat’s physical stock remains separate.\u003c\/p\u003e\u003cp\u003eRebelcell explicitly cites the \u003ca href=\"https:\/\/skysat.fr\/products\/rebelcell-batterie-lithium-36v75-bt-75ah\"\u003e36V75 BT 36075REUABT lithium battery\u003c\/a\u003e as a recommended combination for stable 12 V output. Its 30–42 V range remains within the converter’s 8–42 V input; verify the actual installation, external 25 A fuses on both sides, M8\/M4 terminals, polarity, cables and total load ≤25 A. No specific fishfinder is validated. Do not extrapolate to the 36V105 EDGE whose maximum voltage reaches 43.8 V.","brand":"Rebelcell","offers":[{"title":"Default Title","offer_id":57352916959572,"sku":"DC12V25DCWP","price":172.86,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/rebelcell-convertisseur-dc-dc-etanche-124-v-25-a_dc12v25dcwp-1.webp?v=1790792997","url":"https:\/\/skysat.fr\/en-gb\/products\/rebelcell-convertisseur-dc-dc-12v25a-ip65","provider":"Skysat","version":"1.0","type":"link"}
