PMIC

I'm still too noob to understand about PMICs, I've been looking on aliexpress and I can't find a module.

Will something bad happen to my esp32 if I just put the lifepo4 in a box like this https://www.amazon.com/LAMPVPATH-Single-Battery-Holder-Leads/dp/B07BXX62JF and connect it directly to the esp32 3.3v pin? , I assume that when the esp32 turns off, the battery is discharged and I will need to recharge it again.
