What Our Customer Say
Qianwei Precision are the best terminals. They are heavy duty, built very well, and since they are coated, they are great for automotive and marine use compared to raw copper. They don't oxidize or corrode. They even come with pretty decent heat shrink.
The quality of the sheilding and the material used on the actual terminal is astounding! We use these in car audio and elctrical applications and they are perfectly sized, have a perfect electrical connection, and the heat shrink holds wonderfly!
These battery cable ring lugs are well manufactured and supplied with color-coded heat shrink tubing to clearly identify positive and negative cables. They crimp smoothly, provide a secure hold, and offer excellent value for the price.
Qianwei Precision’s terminals and connectors meet our electrical and mechanical requirements precisely. The products show excellent crimp performance, dimensional consistency, and long-term reliability in real applications.
Qianwei's terminals are exceptionally well made and designed for heavy-duty applications. Once crimped, the connection is mechanically secure and electrically stable, making these lugs a cost-effective solution for professional installations.
