I think you’ll be fine with the led strips. Assuming you’re going to run strips at same schedule that your lights would normally be on? How long are you estimating they will run from the battery?
I think @WillyJ was onto something. They will usually take a hiccup in light schedule. But you really don’t want concurrent hiccups. An extended period of dark or extended period of light within reason shouldn’t really change anything. But if you can hold close to same schedule with leds should be good for sure.
