DIY battery builders, these epoxy boards are exactly what you need for your projects! You get four sheets measuring 20.3cm x 17.2cm x 0.05cm each - perfect for creating custom battery packs and providing that crucial electrical insulation.
The FR-4 material is fiberglass-reinforced epoxy that's seriously durable and provides excellent electrical insulation properties. It's heat resistant and won't break down over time like some cheaper materials. The 0.05cm thickness gives you good rigidity without adding unnecessary bulk to your battery builds.
Whether you're building power tool batteries, ebike packs, or any custom power solution, these boards work great as separators between cells or as structural components. They're easy to cut to size and work with. Much better than trying to improvise with materials that might not be safe for battery applications. Every serious battery builder should have some of these on hand!
