Show original supplier description

The Fastronix Mil Spec Battery Terminal Kit (940-400) provides everything needed for a professional military-spec battery terminal conversion. This kit is particularly well-suited for multiple battery installations commonly found in race cars, off-road vehicles, and RVs, as well as any application where optimal battery performance is essential. The kit includes both positive and negative Fastronix mil-spec top post connectors, ensuring a secure and reliable connection. It also comes with (4) 2-gauge 3/8" copper lugs for excellent conductivity and corrosion resistance, and (4) 3/4"x 1-1/2" adhesive-lined heatshrink pieces for superior cable sealing and protection. To complete the installation and prevent accidental shorting, the kit features a pair of Fastronix mil-spec battery terminal covers, giving your battery setup a professional and finished look.
