Proboat Sonicwake 36" w/ Turnigy Graphene 6000?

[pdegene]

Hi all! This is my first post. I've been in the hobby for over 20 years and prefer boats over any other RC vehicles.

A few months ago, I purchased a Proboat Sonicwake 36" and have been preparing it for spring. I recently bought a set of 3S Turnigy Graphene 6000 batteries. I was not paying attention to the size of these when buying, and the batteries are massive and heavy(630g per). They fit perfectly but I'm concerned that they're too heavy for the hull. I'm not sure if the boat will sit right in the water, whether the self-righting function will still work and most importantly, what will happen when the boat eventually takes flight. I'm concerned that they'll rip out and take the whole boat down.

Anyone running these? What batteries are you running? I'm thinking that I made a poor choice with this purchase and might try to return for something else.

Any info would be greatly appreciated!
