Hi Community,
I have a 10s4p battery pack that is 41V 12ah.
I am trying to build advertisement stands for my business, so I need to power a laptop screen and media box from it.
Someone told me that it is not a good idea as the power source is not stable. Is this true? Surely it is possible as all laptops are powered of these batteries?
This is the components I am using:
The problem is the step down power module only works on the voltage. If I step it down from 41V to 12V the amps gets step down from 12A to 8A which is to strong for the driver board. It overheated. Is there an step down power module out there that can step down both vols and amps?
I am trying to build a screen as per the below link and add it on a stand as per the attached picture.

Any help would be greatly appreciated.
Cheers
