New to NES Modding? Few questions on battery?

Hello all, firstly im new and was following a guide on making a portable NES. I am following this guide and all of it makes sense up until this step.

Im confused on finding a battery, can someone recommend a good battery with the charging circuit for easy install? If i need to buy a whole DVD player i will. I don't need that much Battery life. An hour or two would be fine
Thank you!

Also any other recommendations to a noob would be great. Thank you!

When in doubt, google it! lol There's plenty of sites that sell batteries, I bought my last few items from batteryspace.com. They have tons of rechargeable battery packs, individual cells (for custom pack creation) as well as chargers for them.

Otherwise, you could just set it up to run on regular batteries lol. Just make sure the batteries provide at least 9v.
