How to connect 16.4 Ft RGB Color Changing Kit with LED Flexible to a Battery and waterproof?

I have a project in which I want to connect at least 10 ft of RGB LED waterproof lights to be use in the water.  I bought 16.4 Ft RGB Color Changing Kit with LED Flexible Strip, Controller + Remote and Power Supply, 5050rgb Kit. I  want to be able to connect it to a battery  and use it on my water board wirelessly with a remote control to activate the lights. The kit came with a remote control, but  not sure which battery would be a good choice or where to buy it.  Here is an Idea of what I am looking for http://www.youtube.com/watch?v=_XlioqLlF_g  .I want to make it and I hope you guys can help. Thanks :)

HI there,

What's the link you suggested? I asked around and the is 12v 7 amp. Now, I was wondering if I can use a 12v 24 amp energizer little battery. As you are aware size and weight does matter as I will b using it on a surfboard. Can I put the batteries on a waterproof case with the wiring?
Any ideas we'll be greatly appreciated. Thanks
7A is quite a lot - that's 84Watts of lighting. What battery exactly do you have in mind ?

How long do you want it to be lit for ?

Like I said, have you got a link to where and what you bought ?

Which battery do you recomend I should use? Thanks a lot

How long do you want it to be lit for ? I suggest you use a sealed lead acid battery, in a waterproof case. A 3Ah battery will last one hour, if you have everything on full
You'll need a 4x 3 = 12 Ah battery.

Like this:

...that is at full brightness, and the whole strip, for more than 3 hours.
Did you get any user manual with it ? As it will help you to get all technical answers .
