Then using a powerful electromechanical crimping machine, we crimp each solid-copper end, and finally finish the construction by adding a environmental seal made of marine grade heatshrink meeting MIL-I-23053\/4. Also included are military style corrosion resistant battery connections and a MEGA fuse and holder.
