Epoxy Insulation Board 0.5 x 155 x 110 mm for Battery Packs

Product detailed description

Epoxy insulation board FR4 (0.5 × 155 × 110 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 of every professional LiFePO4 pack.
When prismatic (box-type) cells 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 insulation 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 only 0.5 mm, it provides a 100% barrier against breakdown 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 can withstand the pressures created 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: with a thickness of only 0.5 mm, it doesn't unnecessarily increase the size of your battery. You won't lose precious millimeters between cells, but you'll gain peace of mind.
- Easy to work with: the 155 × 110 mm format can be easily adjusted (cut or trimmed) to the exact dimensions of your cells.
