What size ring opening for a 7/16 battery bolt?

For 7/16" battery bolt you will need to go with 1/2" ring terminals.

I'm looking for 3/16" ring any equivalent? Thanks

Thank you for your question. 1/4 would be the closest size to 3/16.

are the #10 the smallest connectors?

The question is worded "#10"....implying that the question is about the eye size, not the wire gauge, which would be stated as "10ga". So, #10 is not the smallest- a #10 screw is either 0.190", or 0.1875", depending on who you ask..about 3/16". A #6 screw is nominally 0.138", so the #6 terminals are smaller. Smaller number equals smaller hole. Wire gage does get larger with the smaller number. Red (22-18ga) appears to be the smallest available here, gauge wise.

is 3/8 the size of the hole?

Yes, 3/8 is the size of the ring eyelet. Wire gauge range is 16-14.
