Epoxy Insulation Board 0.5 × 300 × 300 mm for Battery Packs

Product detailed description

Epoxy insulation board FR4 (0.5 × 300 × 300 mm) – Maximum protection for your LiFePO4 cells
Building your own battery system? Don't underestimate insulation. This ultra-thin yet extremely durable epoxy board is a key safety element for every professional LiFePO4 battery.
When assembling prismatic cells (box type), they slightly expand and contract during charging cycles. Without proper insulation between the aluminum cell casings, there is a risk of the blue insulating film tearing and a subsequent catastrophic short circuit. Our epoxy board made of FR4 material is designed exactly for this purpose.
Why choose this insulation board?
- Extreme electrical strength: FR4 material has excellent dielectric properties. Even at a thickness of only 0.5 mm, it provides a 100% barrier against breakdown between cells.
- Mechanical stability and abrasion protection: The aluminum cell casings must not rub against each other. The epoxy board acts as a mechanical separator that withstands the pressures generated when cells are compressed in a battery box.
- High thermal resistance: LiFePO4 cells heat up at high currents. This board is non-flammable and stable even at elevated temperatures, increasing the fire safety of the entire system.
- Minimal dimensions, maximum capacity: Thanks to its thickness of only 0.5 mm, it does not unnecessarily increase the dimensions of your battery. You won't lose valuable millimeters between cells, but you will gain peace of mind.
- Easy to process: The 300 × 300 mm format can be easily adjusted (cut or trimmed) to exactly match the dimensions of your cells (e.g. 280 Ah, 100 Ah or 304 Ah).
