The Fiberglass Epoxy Insulation Sheet (Model 3240) is a high-strength yellow insulation plate specifically designed for LiFePO4 lithium battery packs, DIY energy storage systems, and EV battery protection. Made from fiberglass-reinforced epoxy resin, this sheet provides exceptional electrical insulation, mechanical durability, and thermal stability under high-stress conditions.

Ideal for battery pack builders and industrial power applications, this insulation board helps prevent short circuits, overheating, and vibration damage by maintaining secure spacing between battery cells. With a tensile strength of ≥340MPa, it offers outstanding rigidity and long-term performance even in high-temperature environments.

Whether you’re assembling LiFePO4 280Ah, 320Ah, 310Ah, 200Ah, or 90Ah cells, this epoxy fiberglass board is an essential component for ensuring safety, reliability, and professional-grade battery protection. It’s also widely used in solar ESS, powerwall projects, BMS enclosures, and other high-capacity lithium battery systems.
