Really good product - well worth the money.
These lugs work well. They are easy to install and crimp and they've been working great for me for three years. And they're a really nice value for the money, much cheaper than inferior lugs I've purchased locally.

Worked great on my flexible 4 AWG wires for my 24V system
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.
