Tronic Lugs 35mm – 8mm Battery Cable Ends

Our review

These Tronic lugs are battery cable ends sized 35mm by 8mm, built for connections that have to hold up under heat and heavy current. The closed barrel design covers the wire joint rather than leaving it exposed, which helps with insulation and safety, and the flared opening makes it easier to feed stranded cable into the lug before crimping. Because the heat shrink tubes come pre-cut to common diameters, you spend less time trimming and more time finishing the job. They suit anyone rewiring a vehicle, inverter, solar bank or similar high-current setup where a loose or exposed joint causes voltage drop and heat. Before buying, confirm your cable's cross-section and the stud size on your battery terminal or busbar match the 35mm and 8mm figures, since a mismatched lug will not crimp down properly. Compare against open-barrel lugs, which are cheaper but leave the joint exposed, and against pre-insulated types that save a step but offer less control over the crimp. If you already own a crimping tool sized for this barrel, these are a practical choice; if not, factor one in. Available on Sokonia.
