![100mm Tall Genuine Fishpaper](http://18650.club/cdn/shop/products/images_66731017-6468-4630-b6d8-edc285d42444_{width}x.jpg?v=1622406913)
Genuine Fishpaper cut 100mm wide. If you're not using cell holders, you must insulate between voltages (Between P groups) to avoid shorts through the thin PVC factory wraps cells come with.
Our vulcanized fish paper is highly abrasion-resistant, heat-resistant, and adhesive-backed for ease of use.
If you're using cell holders, you'll only need fishpaper on the tops and sides where you run balance cables, so a small amount is suitable. Otherwise, we reccomend about 5cm of fish paper per cell in your pack, + 20% or so extra to cover the edges of the entire pack and balance wire routing insulation.
