Wow you are a wealth of knowledge.

I'm running 4s packs right now and I have a few 2s packs as well. I would like to use 2-4s backs in series and 4s with 10,000mah but only if the motor/esc can take that.

What I'm concerned about is run times and being able to retrive the boat. A friend of mine, who will be with me most of the time, has a small boat that we could use. Other than that I'm on my own.

What would be a good setup for a longer runtime? 10 minutes plus?

Thanks again for all of your help,
Nick
