You may be able to do something like this:
Use an RC/Drone LiPo battery: https://www.hobbyzone.com/batteries/lipo/4-cell/ONXP2459.html
Connect it to a switching Dc-Dc converter: https://www.amazon.com/dp/B06X1DPFQQ/
Now you have 5V, 30A available for your LEDs. Note, things will get HOT running at full power, you'll need a way to cool down the LEDs and the Dc-Dc converter.
Using that battery (75 watt hours), you should be able to power your LEDs (150watts) for about half an hour at full brightness.
Also, Id be very careful working with high capacity Lipo batteries, do your research and take precautions, they can be dangerous if not used correctly (shorting out leads/puncturing the case etc).
You may be able to find a better quality Dc-Dc converter, but make sure its a switching converter as they are much more energy efficient compared to a linear regulator Dc-Dc. 3 of these could also work: https://www.amazon.com/dp/B00VUHVX6W/
Edit: I just realize you need 4 (not 3) * 5V/10A, or 200W power.
Hmm strange, even if your drive needs 0.5 amps on the 5v it’s just 2.5W per drive... if you have a psu with 120w on the 5v rail and reserve 20w for the mobo (enough?), it will still be ok for 40disks... my seagates are at 0.3 amps on the 5v, so fine for 60disks. If really running into issues, a second 5v rail is needed, something like this could do the trick:

Could this be used inside a case (cooling etc)?
