I've seen a lot of these around already. I almost bought a small one about a year ago, but then went in another direction. https://www.amazon.com/12-Volt-Rechargeable-Lithium-Battery/dp/B00JK06CK8/ They're 12v (sometimes 6v) worth of lithum cells, often LiFePO4, with some kind of BMS internally so you can (supposedly) charge them with a lead battery charger. Actually, in many cases all you need is a bare power supply. You have to watch out for them though. There are a lot of cheap Chinese batteries like this that have just "protection" circuits, not true BMSes. The cells soon get out of balance, and the usable capacity falls.
