Permanent Connection to Charging Post

[mboucher70 hotmail.com]

I’ve got a pretty good ‘smart’ charger that’s great for maintaining a car battery, since the car stays parked much of the winter.

The brand is CTeck.  In addition to the usual clamps connectors, it comes with an additional set of eyelet connectors that you’d attach to the battery terminal bolts, and a cable that you’d run to the front grille to easily plug in and out.

Since my Audi has the battery under rear seat, I’d need to attach the eyelet connector to the positive charging post.  Any ideas on a good way to connect an eyelet connector (the small ring) to the positive charging/jumper post under hood?

thanks
MC
