Re: attaching car battery to inverter with 5/16 inch cable ring connectors?

Re: attaching car battery to inverter with cable ring connectors?

The instructions say to attach termnals to posts, however every car battery

so far has posts much larger than 5/16 inch.

I'm guessing the vendors don't distinguish between posts and the threaded

5/16 inch or 1/4 inch screw clamps holding the car's cables in place.
