Review: Excellent Quality, Super Strong and Perect Design - The Best Battery Terminals money can buy. There lugs are extremely well built with good design and top quality material which crimps very well. The lip is thick and holds very well when connected. Size is slightly bigger for the 6 AWG Grounding wire, perhaps because I am using solid copper wire, however, after hydraulic crimping it came out as a champ. Most other terminals sold on desertcart are thin and cheaply made, but this one is very different and designed for tough performance. I already ordered another set to keep them as spare. Recommended to everyone.
Review: Good quality and decent thickness . I prefer the tinned copper less deterioration-corrosion - One of my preferred brand to use for lugs , decent quality and thickness. I’ve made up well over 50 battery cables in several gauges 4/0, 2/0, 4, and 6 mainly using Salterm. So this is a repeat buy. Just beware before ordering is what diameter size hole you will need most will be 5/16 and 3/8 but some 1/2”. If unknown get the 5/16 since you can drill it out if needed…I’ve done that before with this brand and works good. Would not recommend using bigger than needed hole takes away from metal contact which could heat up connection if size wire is marginal small for amps being used. Would recommend and buy again like I have before and now again. Also can used different crimping tools with this brand works with all of them, I’ve used the clamp style where squeezing all around the lug and the punch down style all worked good to crimp.
