I'd recommend skipping the Yongnuo and moving to Godox or FlashPoint (same units). They are interchangeable (signal wise) with Canon and you don't have to do anything special to use them. For model photography when I typically shoot 1,000+ pictures in a session, I use the Godox AD-360 with the external PB-960 battery pack. Setting on AP at f8, the flash will throw out enough light to blind anyone within 20 feet and I get 1-2 second recharge times. Technically, it's supposed to give 500 flashes at full power but from experience, it will go a lot further than that as normally all flashes under TTL are not full power. I usually replace the battery at around 500-600 flashes to hold the recycle time down when it starts taking more than a couple of seconds to recharge. The battery part of the external pack just slides off and you can switch out the battery packs in less than a minute without disconnecting anything.
I've got two Yongnuo 660's (I think) but the problem with them is that the flash rapidly overheats and shuts down like an R5 in video mode. There is nothing worse than hitting the shutter release and the flash refusing to fire. It's been a while but the flash will shoot less than 20 flashes at full power in short order before overheating. My AD-360 is rated for about 80 full-power flashes before taking a coffee break and I've never had that happen during a model shoot.
If you insist on the Yongnuo, you can buy an adapter cable to connect to the Godox PB-960 battery pack ($150) and get instant recharge and rapid overheat! LOL I think the Yongnuo is a great flash especially since they are dirt cheap. If you don't have an occasion to require multiple flashes in short order, it's a good choice. I initially tried the Yongnuo a couple of years ago with the flash trigger and it was good but in actual practice, I couldn't stand the overheating problem. The Godox/Flashpoint is completely compatible with Canon EOS cameras and you can do anything that you can do with the Canon flash in TTL mode.
My setup when I do flash photography is a Godox AD-360 firing into an umbrella with the PB-960 hanging off the tripod. Using the Godox Xpro-C wireless trigger on the hot shoe, I can instantly change the lighting without wires right on the camera. On location with a lightweight tripod, it's easy to move around and being able to shoot at f8 minimizes out of focus and DOF issues. I normally shoot at ISO 100 and f8 on my R5 (1/200th shutter) and even firing into the umbrella, I can light up a room with no trouble. The AD360ii with a power pack is $500 and can work for both studio and fieldwork. You just spent $6-7K on an R5 system, what's another $500?
