For a battery pack you could use some chinese 18650's. They are relatively cheap ($1-2 each) and people use them to build power packs to run as reserves for solar and wind power attached to their houses and tiny homes. Should be doable to wire up a set of them to power a monitor for a few hours without breaking the bank.Heres someone wiring a load of 18650s to replace a Tesla powerwall. You can use the same principle to get the right battery size for your needs.[MEDIA=youtube]T_JesCvR1Rs[/MEDIA]
