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.
