With 280Ah of usable capacity and a hefty 3584Wh of energy in a single 12V unit, this is the battery you reach for when you're powering a whole cabin, a serious backup system. Built-in heating pads handle the cold automatically, so charging keeps going through Central Otago winters, alpine sheds, and frosty Waikato mornings when other lithium batteries would sit there refusing to take a charge.\u003c\/p\u003e\n\n\u003cp\u003eInside you'll find genuine grade A 280Ah prismatic LiFePO₄ cells paired with SOK's own custom-designed BMS — not the generic off-the-shelf board you'll find in most competitor batteries. It handles 200A continuous discharge, 250A peak, and protects against over-charge, over-discharge, over-current, short circuit, and high or low temperature events. The aluminium case is built to take a beating, and the design is fully serviceable — pop the cover, swap a cell or the BMS, and keep going. Most lithium batteries on the market are sealed boxes you throw away when something fails; this one isn't.\u003c\/p\u003e\n\n\u003cp\u003eSOK has been one of the most trusted names in the global off-grid community for years, with a reputation built on transparency, build quality, and batteries that actually do what the spec sheet says. We import directly from the factory and back every unit with our 7 year warranty, with a realistic 15+ year service life when looked after. \u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003e12V 280Ah \/ 3584Wh capacity\u003c\/li\u003e\n\t\u003cli\u003eInternal heating pads with automatic low-temperature charge protection\u003c\/li\u003e\n\t\u003cli\u003eGenuine Grade A Ganfeng prismatic LiFePO₄ cells\u003c\/li\u003e\n\t\u003cli\u003eSOK custom-designed Smart BMS with Bluetooth monitoring\u003c\/li\u003e\n\t\u003cli\u003eMax continuous discharge: 200A (250A peak)\u003c\/li\u003e\n\t\u003cli\u003eRecommended charge current: 56A (max 120A)\u003c\/li\u003e\n\t\u003cli\u003e4000–8000 cycle life, maintenance-free\u003c\/li\u003e\n\t\u003cli\u003ePowder-coated aluminium enclosure with M8 terminals\u003c\/li\u003e\n\t\u003cli\u003eDetachable cover — user-serviceable BMS and cells\u003c\/li\u003e\n\t\u003cli\u003eOver-charge, over-discharge, over-current and short-circuit protection\u003c\/li\u003e\n\t\u003cli\u003eHigh and low temperature disconnects\u003c\/li\u003e\n\t\u003cli\u003eParallel up to 10 units\u003c\/li\u003e\n\t\u003cli\u003eCertified to UL1973, UL9540A and IEC62619 (cells)\u003c\/li\u003e\n\t\u003cli\u003e7-year manufacturer-backed warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy It's a Smarter Buy\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003eServiceable design — replace the BMS or cells instead of binning the whole battery\u003c\/li\u003e\n\t\u003cli\u003eBuilt to last: 15+ year realistic lifespan when looked after\u003c\/li\u003e\n\t\u003cli\u003eLightweight compared to lead-acid — easier to install and rack up\u003c\/li\u003e\n\t\u003cli\u003eFaster charging and 100% usable capacity vs AGM or gel\u003c\/li\u003e\n\t\u003cli\u003eNo off-gassing, no voltage sag, no topping up\u003c\/li\u003e\n\t\u003cli\u003eExcellent thermal stability and very low self-discharge\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0941\/9420\/4973\/files\/sk12v280H-datasheet.pdf?v=1779830666\"\u003e\u003cstrong\u003eDatasheet\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e\n","brand":"SOK","offers":[{"title":"Default Title","offer_id":51705832046893,"sku":"SK12V280H","price":1900.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0941\/9420\/4973\/files\/sk12v280H_800x800-scaled_2efba937-16c8-4bf2-a486-566e9bcd22da.jpg?v=1766033192","url":"https:\/\/checkout.sogenenergy.co.nz\/products\/sk-12v-280ah-heated-lithium-battery","provider":"Sogen Energy Ltd","version":"1.0","type":"link"}
