"Transfers to Other Banks" page.
There is no fee, but you are limited to a maximum of $9,999,999.99 per transfer. (Transfers from investment accounts are limited to $100,000.00 per 24 hours and $250,000.00 per week.)

They've (edit: Discover) advertised Zelle support for a while, but new accounts haven't been able to enroll since at least March 2020.
Since the debit card isn't Visa/MC, you can't even hook it up using the Zelle app.

So it's nice. I wonder if Zelle is fester, but it does not sho up in my Discover account. But I am pleased with the discover transfer option.
Most Banks/CU's have the ability to add external accounts.
Most have no fee for transfers.
All have different daily, monthly and max transfer amounts.
Pushing from one to another is often faster than requesting money being pulled.
If this is going to be a regular event, set up BoA and push the money.
Most of my institutions push every evening and it is at the receiving bank/cu the next day (YMMV).
Pulling money between institutions has a one or two day time warp. (Average 3 day)
Push when possible 
I'd say pull from Discover, BoA has a $3 transfer fee. Do it during the week to make it as fast as possible because it seems it's mostly just processed on business days.
