More information will be updated then!\u003c\/p\u003e\n\u003cp\u003eThis is a Lithium-NMC (lithium-nickel-manganese-cobalt) battery that needs to be modified to be used in a car. It's the same battery that others sell ready-made for significantly more money. In the USA, they are called CMAX. More pictures will be uploaded soon.\u003c\/p\u003e\n\u003cp\u003eNMC batteries have one of the highest energy-to-weight ratios among Lithium batteries. NMC also handles cold better and has about 5-10% more usable power than LFP above +20 degrees Celsius. At -20 degrees Celsius, they retain more than 50-70% of their energy compared to LiFePO4, which often drops below 50%. These batteries should not be charged below 0 degrees Celsius, as this can cause the battery to lose capacity and, in the worst case, destroy it.\u003c\/p\u003e\n\u003cp\u003eThe pack consists of 12 cells, currently connected to approximately 22V (6S2P). Each cell is Max 4.1V, 25Ah, 15C-25C (According to the manufacturer) and is sufficient for approximately 10,000W amplifiers. What needs to be done is to disassemble the battery pack and move the cells according to picture 2 (4S3P), make busbars (existing ones can be modified), and purchase a balancing circuit that can handle NMC batteries and 4S. It can be found \u003cspan\u003ehere\u003c\/span\u003e.\u003c\/p\u003e\n\u003cp\u003eCurrently, we are unable to ship this item. We are working on a solution.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFAQ\u003c\/strong\u003e\u003cbr\u003eWhy are they so cheap: This is a \"Do It Yourself\" battery. It must be modified before you can use it in your car, and no balancing circuit is included; it must be purchased separately \u003cspan\u003ehere\u003c\/span\u003e..\u003cbr\u003e\u003cbr\u003eAre they new: No, these battery packs come from dismantled electric car batteries.\u003cbr\u003e\u003cbr\u003eAre they tested and OK: Yes, they are tested and are OK. OK means they have more than 70% of their original capacity remaining.\u003cbr\u003e\u003cbr\u003eAre they flammable: Yes, NMC batteries can burn.\u003cbr\u003e\u003cbr\u003eCan they be used in winter: You can use them to draw power, however, performance is reduced. Charging them is not recommended below 0 degrees Celsius.\u003c\/p\u003e\n\u003cp\u003eWarranty: Yes, for 3 months against cell defects.\u003c\/p\u003e","brand":"SPL-Systems.se","offers":[{"title":"Default Title","offer_id":54002321719635,"sku":null,"price":1500.0,"currency_code":"SEK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1079\/3569\/5187\/files\/320128021_6129914973740049_213412103064324314_n.jpg?v=1781516890"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1079\/3569\/5187\/collections\/5815737959.jpg?v=1781429747","url":"https:\/\/spl-systems.se\/en\/collections\/batterier.oembed","provider":"SPL-Systems.se","version":"1.0","type":"link"}
