Can I connect charger directly to battery?

Do not do this. The battery is only meant to be charged by a charge management chip in the phone. That chip regulates the flow of electricity into the phone, preventing it from charging too quickly or to too high of a voltage. If you connect a power supply directly to the battery terminals, the battery may overcharge.

Can you charge two batteries one alternator?

You can run two batteries on the same alternator. Alternators protect against excessive current drain and aren’t affected by multiple batteries. The alternator registers these two batteries as a single large battery and charges them the same. The batteries self-regulate the amount of current they take as they charge.

Are battery to battery chargers any good?

Battery-To-Battery chargers (also commonly know as DC-DC chargers) allow you to charge an auxiliary / leisure battery from your alternator whilst driving.
