Don’t underestimate the importance of insulation. This ultra-thin yet extremely durable epoxy board is a critical safety component of any professional LiFePO4 pack.\nWhen prismatic (box-type) cells are assembled, they undergo slight expansion and contraction during charging cycles. Without adequate insulation between the cells’ aluminium casings, there is a risk of the blue insulating film being worn through, leading to a catastrophic short circuit. Our FR4 epoxy board is designed precisely for this purpose.\u003cbr\/\u003e\u003cbr\/\u003eWhy choose this particular insulating board?\n- Extreme electrical strength: FR4 material has excellent dielectric properties. Even at a thickness of just 0.5 mm, it provides a 100 per cent barrier against breakdown between cells.\u003cbr\/\u003e- Mechanical stability and abrasion resistance: The aluminium casings of the cells must not rub against one another. The epoxy board acts as a mechanical separator, withstanding the pressures generated when the cells are compressed within the battery box.\u003cbr\/\u003e- High thermal resistance: LiFePO4 cells heat up at high currents. This plate is non-flammable and remains stable even at elevated temperatures, thereby enhancing the fire safety of the entire system.\u003cbr\/\u003e- Minimal dimensions, maximum capacity: Thanks to its thickness of just 0.5 mm, it does not unnecessarily increase the size of your battery. You won’t lose precious millimetres between the cells, but you’ll gain peace of mind.\u003cbr\/\u003e- Easy to work with: The 500 × 620 mm sheet can be easily cut to size to match the exact dimensions of your cells (e.g. 280Ah, 100Ah or 304Ah).\u003cbr\/\u003e\u003cbr\/\u003eTechnical specifications:\n\n- Material: Epoxy fibreglass resin (FR4)\n- Dimensions: 500 mm × 620 mm\u003cbr\/\u003e- Thickness: 0.5 mm\n- Colour: yellow\n- Application: Insulation between prismatic cells, busbar protection, separation of the BMS from the cells.\n\nPackaging: 1 piece","brand":"TIPA","offers":[{"title":"Default Title","offer_id":54174460739922,"sku":"06570138","price":185.0,"currency_code":"CZK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0954\/9624\/1490\/files\/06570138.jpg?v=1785826610","url":"https:\/\/tipa-production.myshopify.com\/en\/products\/epoxy-insulation-board-0-5-x-500-x-620-mm-for-battery-packs","provider":"TIPA","version":"1.0","type":"link"}
