12v and 14v alternators are usually the same. It's a 12v system that needs to charge around 14.7v. 

200 amps, you're going to need 2. Going to have to get a dual alternator bracket made

You shouldn't mix lithium and AGM. They have a different discharge and charge rate, and they rest at completely different voltages. It'll just cause problems.

400 amps of charging and 1 100ah lithium should be more than enough.
