Power computer with lipo bateries

Hi I want to run a PC off of lipo batteries so that I can make a portable PC based laptop

I so far have found DC to DC converter called the PicoPSU that will run the computer on 12 volts at 200 watts but I cant find a 12v power regulator that has that high of a wattage.

Pretty much I need continuous 12v at 200w from lipo or other compact batteries.

Thanks Max

The PicoPSU needs a regulated 12V supply - if its input goes over 13 V it shuts down.
Li-Po batteries don't generally output 12V - when they do it usually means they have a built-in DC-DC converter, but it is not likely you will find one that can output 20 amps.
Lithium iron phosphate batteries like BTL14A240C might work.
There are lots of power supplies like that can output 12V at 20 amps. A search should find many.

Unfortunately the BTL14A240C is far too big but i did come up with another idea
would doubling up 2 of these variable 10 amp converters work each with their own battery?

I think it will be tough to get two of these to share power and they are already very marginal at supplying enough power.
Check out the M4-ATX 250W with a wide range of DC input voltages.
