Powered by a rechargeable lithium battery instead of gasoline, it eliminates the fuel can, pull cord and exhaust fumes while delivering variable-speed breathing air to up to four divers from a single floating platform. The compressor responds to demand automatically and shuts off when the system reaches its pressure setting, extending battery life and keeping surface noise to a minimum.\u003c\/p\u003e\n\u003cp\u003eBuilt in South Florida by the team that pioneered the Original Gas tankless dive system in 1969, the Sea LiON carries decades of Brownie's engineering into a battery-powered design made for boat days, beach dives, lobster season and any underwater adventure where you want to bring the whole crew. Brownie's quick-release QRS fittings keep hoses organized and diver swaps fast, while the removable battery pack splits the approximately 53 lb assembly into two manageable pieces for easy loading and unloading.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery-Powered, No Fuel Required:\u003c\/strong\u003e Rechargeable lithium battery replaces gasoline - start with a push of a button, no pull cord or exhaust fumes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable-Speed Compressor:\u003c\/strong\u003e Automatically responds to air demand and shuts off at its pressure setting to conserve battery energy between diver breaths.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccumulator Tank:\u003c\/strong\u003e Acts as an air buffer so divers breathe smoothly from stored volume while the compressor cycles to refill - no air interruption.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupports 2-4 Divers:\u003c\/strong\u003e One floating platform supplies individual air hoses to two, three or four divers simultaneously (four-diver use limited to 10-15 ft depth).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRemovable Battery Pack:\u003c\/strong\u003e Battery separates from the floating unit so you can carry the system in two lighter pieces and swap charged packs between dives.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrownie's QRS Quick-Release Fittings:\u003c\/strong\u003e Proprietary quick-release connections make adding, removing and organizing diver hoses and equipment fast on the water.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePeleton-Style Hose Arrangement:\u003c\/strong\u003e Each diver receives a dedicated individual air hose from the surface unit, keeping everyone connected and organized.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e~53 lb Assembled Weight:\u003c\/strong\u003e Approximate operating weight with battery installed - lighter than a comparable gas system with engine and compressor combined.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions: 33 x 19 x 36 in:\u003c\/strong\u003e Compact floating footprint sized for use from a boat deck or beach launch.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade in South Florida:\u003c\/strong\u003e Designed and built by the Brownie's team with replacement parts available and authorized service centers nationwide.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch2\u003eBattery Options \u0026amp; Which to Choose\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e50Ah Battery (~2 hr 15 min):\u003c\/strong\u003e The standard included battery is the right pick for half-day dive sessions, casual boat days and situations where you plan to bring a spare pack or keep dives shorter.

These are estimates and will vary based on depth, the number of active divers, individual breathing demand, water conditions and battery age.

The Sea LiON's battery is designed to be removed and swapped without moving the entire floating unit. Spare 50Ah and 70Ah batteries are available as add-ons, each including their own charger and protective storage case.

It is supplemental equipment and does not replace training or proper dive planning, but it adds a meaningful layer of backup for divers going beyond depths where they would be comfortable with a free-swimming ascent. It is available for 2-, 3- and 4-diver configurations.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e","brand":"Brownie Third Lung","offers":[{"title":"50Ah Battery (~2.25hr)","offer_id":56517138710833,"sku":"SEALION-50AH","price":6079.95,"currency_code":"USD","in_stock":true},{"title":"70Ah Battery (~3hr)","offer_id":56517138743601,"sku":"SEALION-70AH","price":6579.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1724\/7681\/files\/Sea-LiON-Black-Inner-Pan-WooCommerce.webp?v=1790614158","url":"https:\/\/omahasportsandgames.com\/products\/brownies-sea-lion-battery-powered-tankless-dive-system","provider":"Omaha Sports \u0026 Games","version":"1.0","type":"link"}
