What explains the x2 price difference between those two batteries?

[Reliquat]

Same brand, same specs, same website, twice the price, am I missing something?

https://hobbyking.com/en_us/turnigy-nano-tech-plus-5000mah-3s-70c-lipo-pack-w-xt90.html 35,98 €
https://hobbyking.com/en_us/turnigy-battery-nano-tech-5000mah-3s-65-130c-lipo-pack-xt-90.html 75.86 €

Prices are $36 and $64 when I set location to USA but still?

Might just be the more expensive one has a higher discharge rate. That's the only difference I see.

more expensive clearly says on shrink wrap ,matched cells

So matched indicates they balance themselves and a balance plug isn't needed?

Sorry, newbie still on some things and just trying to learn!

I see the cheap one with 70/140C and the expensive one with 65/130C

I can't find this information but does it justify double the price?

I found in the specs tab that the expensive one has a 8C charge rate, could be the reason? (never seen a lipo with such a high charge rate)

When a LiPo is put under load, the voltage will decrease. The 130C battery will hold its voltage at a higher level under load than the 70C. 70C is adequate for most bashing. 130C for really heavy longer WOT (Wide-Open Throttle) demands. Hope this helps. Cheers. 'AC'

higher price is for matched cells. both have same ir and mah rating

As said above the cheap battery is 70/140C and the the exepensive is 65/130. Interesting explanation tho

Are some lipos sold with unmatched cells?

For those of us not in the know, what does "matched cells" mean? I'm guessing produced in the same batch, but never really heard the term before.

And why would they make "unmatched" lipos? Tntpoof, please educate us!

This is the answer you gave. Okay.. so the one costs more bc it's "matched".....we get that but were hoping you could share your experience and expertise and explain what that meant. But instead you act like a douche and keep referring back to your lame a$$ 1st answer.

We love this hobby and are just trying to learn from experts. You obviously don't care about teaching others.......so why the eff you even on here? I've seen some of your other grumpy mean posts to other members here. No wonder this forum is not as busy, because people like you push newbies away.

You wanna troll someone or not be helpful to newbies, then get on Twitter or Grindr or some other site where douche bags sit around and don't help anyone. Sad......just sad.......I hope you find peace and happiness in your life. I'll keep you in my thoughts and try to send good karma your way. Sounds like you need it.

Okay, enough negativity for me today. Enjoy your 4th butthead!

I've been under the impression that balance charging 'matches' the cells. Is there a selecting and culling process at the manufacturing level refining that?

Back in the round cell NiMh days, matched cells were the hot set up for the higher levels of racing. Not so much so at the club or bashing level. Is that the thought process here carrying over to LiPo?

Enjoy your 4th, guys. 'AC'

My guess would be that "matched" means they took the time to really measure all the aspects of each cell that they can and bundled the ones that were nearly identical up into packs. IR, capacity, weight and whatever else they can verify. You end up with very stable packs that are more likely to perform as expected throughout their life. Odds are it's a percentage thing. A normal pack has cells that are within 10% of some grey area that makes them suitable. Matched cells are within 1%.

Now that answer made sense. Thank you.
