Both of those are regulated mods , so you have a fair bit of safety built into them.On single battery regulated mods I have the best luck with Samsung 30Q or the Samsung 25R but I am sure there are many batteries that would work well.
Gearbest may be fine but like @JMak642 posted I prefer to buy batteries from the ones I know that I will be getting an authentic.

Don’t, good battery and one of 2 batteries recommended for use in our devices, however, that price is High. You can do better. Ask some of these guys where the best price is…
EDIT, Good, I see you found better prices, carry on…

I think it is $14 for 4 batteries. I thought the same thing at first, but if that’s the case it’s not bad. Kinda tempted to order some myself at that price.

@ringling yeah, what JoJo said, it was 13.99 for four. But quite frankly whether they’re the real deal or not, I already didn’t want to order there once I realized it could take a month to ship! I kinda want these things right away. 
rtd was under $6 a piece including shipping. I’m cool with paying that, especially since people have vouched for their authenticity.

I use, sony VTC5’s, LG HG2’s , Samsung 25r’s and AWT IMR 40a’s , I’ve never had any issues with any of them, all great batteries but I always buy from the most reputable people I can find, usually a guy called ‘Torchy the battery boy’ I always know they’re legit from him, he prides himself on his reputation

I recently got four from Amazon free shipping for $20. They were authentic.

That’s good to know. I was actually wondering about Amazon. I order tons of stuff from there, and you really can’t beat two day shipping if you can find it on prime!

Sorry I am late (critter relocation), but looks like you got it sorted.
I buy 18650 's from Illumn, Gearbest, Amazon, etc. , never any problems if you pay attention to what you are buying.
My Opus and SkyRC will check the batteries for legit, and I test each one before putting them in service.
Since the 18650 shortage was over, it’s rare now to find fakes, although it’s possible. I suggest you buy a IMR or above.
The ICR you screen shot above is fine, just not common generally, the INR will work but is only a 2000mah storage.
There really is a lot to know about 18650’s technically, and you , as usual, were very wise to ask here first before diving off the cliff. Now that you will be set for a while, you can take your time to research about batteries…we already have some great discussions here on ELR, but I don’t remember where…@jojo is the wizard for that info.
Some info is more technical than you need, but good to know. It really is part of what we do here…understanding what/why we use.

I only get Batteries two places. I know I’m getting what I order and willing to pay the slightly higher price considering what a cheap old inferior battery can do to a mod.

For the reason that there are more fakes batteries than genuine ones on the market, we all get from those who we trust. I paid $6.16 for single cell with a coupon saving 10% on vaporsolo.com, so far so good!

We’ve got a ton of those. that’s the battery of choice in this house. They have them for $5.00 at both Imren and IMR regular price.

I have had to send back some to EVEN the most trusted places…
If YOU [any you] don’t have a charger that will test your new batteries, or you don’t know how, then you should NOT CLAIM that ANY BATTERY is a fake, re-wrap, or authentic.
I don’t rely solely on the SkyRC or the Opus, more on the scopes…but it’s a good place to start.
Regurgitating heresay [from wherever] does NOTHING positive for the vaping community. Doesn’t matter if you buy an 18650 for $4-$5-$10/ea…there is NO GUARANTEE that you get a good battery if you don’t test it.
Batteries are an expensive part of vaping, and I see most vapers on a limited budget, why would anyone want to steer them in the wrong direction ? To regurgitate so you seem knowledgeable? Just don’t, eh?
If you wish to learn about batteries, and teach others, learn about them first. First step, go to the battery university,
