Default Building an RC boat

Hi all! I'm an engineering student building an RC boat from scratch for a project. I'm trying to figure out what kind of battery I need. Can anyone help me narrow it down? It's going to be a monohull boat that doesn't need to go fast but I would like it to be able to run for a few hours without needing to be charged. I'm just not sure where to start because there are so many different batteries.

If you want HOURS of runtime, you're going to need a large battery and a small motor or low rpms. Some of the Scale RC boats have larger Sealed Lead Acid batteries and they can run all day at low speeds.

Today's RC main battery tech is Li-Po. They have huge capacities for their weight. You can find 2s(2 cell 7.4 volts) 6000mah batteries for around $25 on Amazon.
