Which one is correct in terms of grammatical rule and punctuation?

Although the book was written by a famous author, was easy to read, and was packed with practical advice, I found it boring.

That is correct parallel construction. The book was:

- written by a famous author.
- easy to read.
- packed with advice.

The book was three things, and you listed them. (Use commas to separate items in a list of more than two.)

Although the book was written by a famous author, it was easy to read, and it was packed with practical advice, I found it boring.

That is not. Do you see why?

Google grammar parallelism.

Maybe because of comma splice. Am I right?
