thunderpower is probably still the best in terms of living up to the C ratings. They are the go-to battery for big 12s helis, but very expensive.
A single 6s 5000mah battery is over $200.

Anything else (hyperion, zippy, any hobbyking battery etc) is going to be "reliable" if it arrives at your house at 3.8v per cell and you don't mistreat it.

FPVers tend to want to optimise for flight duration not top speed, so you pick the lightest name brand battery that is currently in stock. A 20c battery is usually more than enough.

I switched over to Gens Ace from Thunder Power. So far Im happy with them. They are cheap compared to TP's and I can get them warrantied here in the states if I get a bad one. 4s 3300 25c for $31.

Dualsky GTS 45C packs from 2Dogrc/ other vendors. They are unreal. Blow the pants off every tp battery I've ever used, and I abuse them too. Put 2800mah into my 2650mah packs yesterday, and they have WAY les voltage sag than any other pack I've seen. I gained almost 50w on my Zeph just by switching to these from Turnigy nanotechs.

+1 Gens Ace have a VERY good reputation for providing 95% the performance of the very best, but at a fraction of the price. I have some and when required, I'll be buying more.

The " Name Brand " LIPOS are a ripoff. They are good quality, but I will not pay FOUR TIMES as much for a name brand when I can get a Zippy that works just as well and lasts about the same amount of time. There are bad ones out there to avoid, but Zippy from Hobby King has a good reputation and reviews from users, and a very good price. All LIPO's are life and time limited, and you do not get your moneys worth buying the super over priced ones.

It's true that R/C car requirements (regarding C rating and weight) differ from ours, but never-the-less, the below 'shootout' tests are interesting and still relevant when judging the quality of the brands

I wouldn't agree entirely here. As with most things in life (Hi-Fi, cars, etc.), lipo batteries follow the law of diminishing returns. i.e. if you pay twice as much, you will NOT get a battery which is twice as good.

I've bought crap batteries before where the 2-core cable has been 14AWG rather than 12AWG gauge, they've folded at a fraction of their C rating (I've bought 2 x 4000mAh 3S '25C' batteries which both crumbled at 5C) and rarely do cheap batteries hold the capacity the say. My experience is that an 'average' (i.e. not dirt cheap) eBay 4000mAh is more like 34000mAh, but at least I can now factor that in when buying.

Yes a battery which costs twice as much may only give you 10% more performance, but as long as you're happy that in a race your plane, car etc will only ever have 90% the performance of your competitors', that's fine.

If you compare voltage under load to decide which battery is better, make sure that (a) the battery has the same capacity and (b) the load is the same.

Anyway for FPV use weight per MaH to decide because 90% of the time you are running them at 1c, not 20c+. You want to fly for 1 hour or 3 minutes? if for 3 minutes, then buy the ones that work best at 20c..

Those shootout tests compare (amongst other things) what the quoted capacity is with the actual delivered capacity, so this is just testing the battery against itself (so to speak), thus as stated, the tests are still relevant to us when judging the quality of the brands.

Also, I typically use 3S 4000mAh batteries and I've yet to encounter a 'no brand' 20C battery which can deliver 80A. Personally I take most quoted C-ratings with a massive pinch of salt.

If you need to draw 80A from a 3S 4000mah battery plane you are not representing the average FPV pilot. Heck, at 80A that full charged 4000mah battery will be completely emptied (dead) in 3 minutes.
Must FPV users will enjoy long flights, happily cruising along at a low power consumption while taking in the scenery. For such applications there is no need for high prices brand lipos. And if you are to far out and have to totally drain the battery to get home, I would much rather destroy a cheap battery.

That's not the point I'm making...

It's been said most people can fly off 1C. Well if what the manufacturer is claiming is 1C *is* 1C- then PERHAPS. I'm saying I don't believe most manufacturers' quoted C-ratings, but if you do, then you should be happy to buy and fly with super cheap eBay 5C or 10C batteries, but I bet no one does. I've bought 15C batteries which have folded at 5C.

I've bought these exact batteries before, which if you believe the sticker should be good for 60A continuous. Well, the ESC on my Easy Star shut down when it requested just 23A (< 6C) at launch from a fully charged pack.

I would much rather have a battery which is consistent and delivers what it promises.

I fly Zippy's and Turnigy's, and i wouldn't trust these ebay battery's either.

but I have to say we lost a plane in a tree and well only thing gone is the battery:

total damage: 9$.

I prefer having a "25C" 3s 2200mah running at 25 amps MAX, it give me a good margin
against an inflated "C" rating but i never had a problem with all 8 of them.

Certainly THERE ARE NO BETTER batteries for the price than Zippy's and Turnigy's.
If you want to have slightly more performance/life and waste your money then 'brand name' lipos are the way to go.
