Featured Best 11.1v LiPo Battery Money Can Buy

Hey guys, I saw a very similar thread but didn't want to hijack it, and plus, my question is slightly different:

If money or cost was not a consideration, what 11.1v LiPo stick type battery would you get? Which one would provide the maximum ROF, trigger response, last the longest without recharging, and is the most durable?

I am looking to replace my Tenergy 11.1v 20c 1000mAh stick type batteries: https://www.ebay.com/p/18012043751?iid=164002024759
I need to make sure they will fit in my buffer tube and AK battery compartment (the type above the gearbox in the receiver). This is an important airsoft investment, so I want to spend the money and get the best possible result, but the most expensive battery on the market is not necessarily the best option.

One other thing, please provide links to the batteries you are speaking of.

Thanks in advance, OA.

 

Where can I get one of these "Kypom" packs? Would they fit in this gun:

(This is not my gun but it is the closest available link)

 

Do you have those in 11.1v?

 

Let me know when you get more and I would be interested.
Would they fit the gun that I linked to earlier?

 

Thanks, Guges. Any idea on the price I would be looking at for a 3S?

I also have another question, but didn't want to start another thread for it: What are the best goggles when it comes to airsoft? I'm looking for ones that will never fog no matter the temperature.
