Epoxy Insulation Board 0.5 x 200 x 170 mm for Battery Packs

Product detailed description

Epoxy insulation board FR4 (0.5 × 200 × 170 mm) - Maximum protection for your LiFePO4 cells
Building your own battery storage system? Don't underestimate insulation. This ultra-thin yet extremely durable epoxy board is a crucial safety element in every professional LiFePO4 pack.
When prismatic cells (box-type) are stacked on top of each other, they slightly expand and contract during charging cycles. Without sufficient insulation between the aluminum cell casings, the blue insulating film can be punctured, resulting in a catastrophic short circuit. Our FR4 epoxy board 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 just 0.5 mm, it provides a 100% breakdown barrier between cells.
- Mechanical stability and abrasion protection: 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 the battery box.
- High heat resistance. This board is non-flammable and stable even at elevated temperatures, increasing the fire safety of the entire system.
- Minimal dimensions, maximum capacity: at just 0.5 mm thick, it doesn't unnecessarily increase the size of your battery. You won't lose valuable millimeters between cells, but you will gain peace of mind.
- Easy to work with: the 200 × 170 mm format can be easily adapted (cut or trimmed) to the exact dimensions of your cells.
