Your link goes to the generic PCPP page; you need to paste the 'permalink'.

Unless your PC is very low power, this is quite hard to do right. Lithium batteries are very touchy about being mistreated - overcharge, overdischarge, overheat, charge wrong... they like to catch fire.

I'd suggest getting a laptop, or a UPS.
