What batteries should I get

I'm building a 43" catamaran and have purchased the leopard 4082 2200Kv x2 with the seaking 180 be esc , need help with info about what batteries should I get with this combo? Thanks in advance

Imo, these are 4s motors so I would get revo packs right here from steven. What is your cat? If it's a Aeromarine Conquest motors may be to small

Thanks
I'm building one from scratch
New at this but from what you saying these motors might be too small for the boat ,it's a dual set ?
