The lithium batteries I'm planning to use have a maximum discharge current of 20A.With Lithium cells, you have to be mindful of the instantaneous current demand, not just the average.

Yes it is 100ms per second, so if I take the previous comments about the accepting the fact that if I power them directly from the battery, they will dim, and knowing the battery can handle the 5.6 amp then I should be ok right?Sure...similar, but 30 watts?
I don't think Papa's calculation accounted for the pulse, which would reduce that 10 amps to 1 average.
100ms per second...right?
I think the 5.6 needed for the 3 watt LEDs divided by 10 is reasonable, that's about 560mA average.
I have no idea how long the charge would last.
SMPS (Switched Mode Power Supplies) are among the most complicated and difficult to understand circuits out there, because there is so much going on. I got my Master's degree in electrical engineering in 1970. It has only been since I retired in 2014, that I have spent any time in the study and understanding of them. I consider myself a mere dabbler having just scratched the surface.Again thanks for your comment, I must say that I didn't wake up one day and say I want to build a rocket ship. This seems a rather simpler project, yes it is over my current knowledge and that is why I'm posting this.
Thank you any way.
And you don't want to have them spend much time discharging at that rate or they won't last very long. It's your time and your resources so go find out the hard way. Blow things up and burn them down. You're only young once. Never mind learning things before you leap into the abyss.The lithium batteries I'm planning to use have a maximum discharge current of 20A.
You are missing the point, the first thing I said in the first post is, I know this isn't right.And you don't want to have them spend much time discharging at that rate or they won't last very long. It's your time and your resources so go find out the hard way. Blow things up and burn them down. You're only young once. Never mind learning things before you leap into the abyss.
