Bit the Bullet ordered the FF today

Skimming through Cabelas site today I noticed they were doing a 0% interest 1 year for purchases on your Cab Visa.  I couldn't resist so on the way is a Humminbird 565 and Icom IC-M34 Vhf.  Now comes the hard question where to mount the battery pack?  I noticed my buddies T13 angler has a battery caddy in the bow from the factory.  Of course I was too cheap and bought a non angler so I could do all the cutting.  It looks like the caddy is a nice way of doing it.  Has anyone seen these for sale?

havent seen them for sale yet. i just have my battery in a watertight box and sit it inside the front compartment of my T13 and i dont have the angler version either.  i have thought about making a pool noodle or foam try and mounting that in there so all i have to do is sit the battery in it plug it in and go.
