Why do you need 10,000 mah?
Why not just sell the motor and go for a lower kv.
You will destoy that motor, when that goes, so can the esc, so can the rx, so can the servo, so can the lipos, not to mention what the hull will look and smell like.
At that much rpm, when the boat/prop hops out of the water and unloads, then re-enters you're going to se MASSIVE amp spikes.
The motor won't run efficiently in that configuration either. It will heat up, and lose power. That is if it doesn't de-mag first.
What boat is this?
