  • Worked great on my flexible 4 AWG wires for my 24V system
Size: 4 Awg - 1/4" (M6) Color: Bare Copper Number of Items: 10
I recently used the 4 AWG Terminal Connectors Ends for my 24V DIY power bank system, and they worked great! These heavy-duty connectors fit perfectly on my flexible 4 AWG wires, providing a secure and reliable connection. The dual wall adhesive heat shrink is a standout feature. It shrinks down tightly, providing excellent insulation and protection against moisture and corrosion. During testing, I found that the heat shrink worked nicely, sealing the connections effectively without any issues. The build quality of these connectors is impressive—they feel sturdy and durable, ensuring long-lasting performance. So far, I have no complaints about their functionality. They’ve proven to be a reliable and efficient solution for my electrical projects, and I wouldn’t hesitate to buy them again. If you need robust and reliable wire lugs for your battery cable or power bank projects, these connectors are a great choice. They deliver excellent performance and peace of mind, making them a valuable addition to any DIY toolkit. ... show more

  • Good Quality
Size: 8 Awg - 3/8" (M10) Color: Bare Copper Number of Items: 6
Good quality seamless connectors. Heat shrink seems to fully seal where it attaches to the wire and connector. Crimped well and provided a secure fit.

  • Solid and heavy
Size: 6 Awg - 1/4" (M6) Color: Bare Copper Number of Items: 10
Nice, solid copper, solidly made. The weight I was wanting. The only thing that would make it better is if the end was flared for easier wire stands entry. One crimp and the connector was solid on the wire.
