I don't think you need a really big battery to do this, because LED lights use very little current.
I'm building several 2' long LED light tubes using the 16' - 600 LED strips from Amazon. I want to make these "self contained" with their own power source, independent of my boat batteries. I need suggestions of what type and size deep cycle batteries that would give me 8 - 10 hours use on a charge, yet be compact and easily moved in and out of the boat. They must be deep cycle, because I will be charging them 3 - 4 times a week. I've been looking at the Sealed Lead Acid type (like in the kids power wheel toys), but not sure they have the amp/hrs to provide the power for what I want. I put a meter on my lights and they are pulling 1.45 amps. What are some of you guys using??

I use a small motorcycle battery, and will run way longer than you'll need it

Does it hold up being charged constantly and not being a Deep Cycle Battery? It will be used 3 - 4 times a week and be on trickle charge constantly (like TM batteries in a boat). I always lost the water in regular batteries and collapsed the cells using non deep cycle batteries on trickle chargers.

I have some solar powered string lights that judging by the weight of the solar panel and battery unit have pretty small batteries. They run 15' strings of leds all night. I'm pretty sure they are lithium ion.
