There are a few other new items added to our store site. We've got two new sizes of black heatshrink, including 20cm wide which fits snugly on smaller 8Ah NiMH batteries, and a large 28cm tube that can even stretch over our triangular layout packs. There are 70oC thermal switches useful for overcharge protection for people building or repairing battery packs, and rolls of self-adhesive silicone tape for effective sealing and waterproofing of exposed electrical connections.
