Recommendation: 6V voltage regulator for a power supply

Hello! I’m looking to build a small, portable power pack out of some recycled 18650s that I have on hand. My plans is it put 4-18650s in a 2s2p configuration with a BMS. I’d like to step down that pack from the 7.4v to a steady 6v. Could someone recommend me a reliable voltage regulator for this application or where I could look for this?

Any help would be greatly appreciated. Thanks!
