Anybody ever used something like this before ? I'm guessing this is a generic brand should one be looking for a certain name brand on a tool like this ?

Looking to switch some things over to group 31 stud type batteries and do away with expensive specialty cables that arc over time on the posts or get loose and corroded all the time.

Would be nice to be able to make your own replacement cables anytime you needed to also. Just wondering on how well they crimp the ends on and how secure and durable the crimps would be. The hammer strike style crimpers are okay but they don't crimp the lug on all sides. Also how big of cable would this work on . The specs seem a tad confusing without referencing to actual cable sizes.

On a some what related question how big a battery disconnect switch would be needed for two 12 volt 1000 CCA batteries in parallel. Most disconnects don't seem to be rated very high or are time limited for only a few seconds. Any web links to a very heavy duty type disconnect switch ?

Thanks for any input.
