The power supply on mine is rated at 24 Volts at 30 Watts (which equals 1.25 Amps). It has a pretty standard power connector on the end that plugs into the controller.
This can supply up to 10x 1 metre sections at maximum brightness, and the controller.
So you could probably achieve what you want with a battery pack of 16x rechargeable 1.5 volt AA batteries (e.g. Eneloop AAs which hold around 2500mA/hour each), which would give you 2 hours of power (2.5A/h / 1.25 hours = 2) at maximum brightness across 10x 1m sections.
You don't say how long your LIFX Z strip would need to be, or what colours you intend to use, but for example just having it on all red (the most efficient colour) uses less power than having them on certain whites (where both the white LEDs and RGB LEDs are lit). It stands to reason if you are only using 5 sections then you would get around 4 hours from the battery pack at maximum brightness.
Note that rechargeable batteries often drop to around 1.2 volts under load, so you may need 20 AA batteries. Rechargeable are preferable to disposable batteries as they keep a reasonably constant voltage throughout their discharge cycle, then the voltage drops off quickly at the end. Disposable batteries drop off in a more linear manner, so they'll drop from 1.5V down to 0V over that same period... so after an hour of use they may be only giving out, say, 1V each - that's a problem.
You can get battery packs that hold a number of AA batteries, like this one that holds 8 https://www.amazon.co.uk/HALJIA-Battery-Holder-Stack-Double/dp/B06Y1LGB42/ and you can just wire multiples of those, or different sizes, in series to get the voltage you need. For example two of those in series will give you 16 batteries in series. You could add a 4 one too to give you 20.
OK - so now you have a powered up LIFX Z. But remember you need it to connect to a WiFi network, that's on the same SSID as your phone (if you're controlling it from there).
