What are the best lipos?

[Metallover]

I've been working on a spreadsheet for awhile comparing capacities of different lipos to see if they use the same cells. Only progress I made was that the Enerland 25c XP cells were used in Flightpower evo25 packs and Hyperion Litestorm packs. Also, the enerland 30c XQ cells are used in Flightpower evo30 packs and Hyperion LVZ packs.

Another possible, more up to date connection would be Hyperion G3 CX 25c packs and flightpower EON-Lite 25c packs. The 1300,1600, 2100, and 2500 capacities are the same. The Hyperion G3 VX pack is 35c and the Flightpower EON-X 30c packs have different C ratings, and Capacities reflect that. The two companies could be using the same cell manufactuer.

I looked into Neu and I was surprised. They have a 40/70c SP series along with a 35/60, 30/60, and 25/50 series. They don't match up with any other cells, and I'm thinking Neu makes their own cells, but I can't back that up.

I'll post the spreadsheet when I finish it. I only have Neu, Flightpower, and hyperion on there now. I still need to add enerland cells. I might get it done tonight...

I might add other companies too, just ask. Thinking about thunder power... I have maxamps on there too... They suck and all their numbers are odd-balls. They truely suck. They don't advertize C ratings prominately because they prey on noobs who don't know to look for c ratings...

So this might be worthless info to some people, but it might help other people out. I'm looking forward to seeing info from BrianGs battery testing station if that gets up and running. The point of this thread is to decide which battery company is the best and try to connect companies with the same cells. In other words, I'm bored.

DUDE!!! You've got to add RCM packs to the spreadsheet!

[Metallover]

Here's what I put together. It's a "first draft". Tell me if anything is wrong.... I might be able to get this as a google docs thing or somethin....

Fourth try's the charm.

man you've got a lot of spare time on your hands...

[Metallover]

Yeah, 2 hours goes a long way. Or was it 3 hours?

I'm pretty dissapointed because I don't think Hyperion and Flightpower use the same cell manufacturer. I don't see any other connections either...

We just need someone who's taken apart packs to chime in and tell us what they've seen. Where the cells were made...

Maybe I'll combine some discharge graphs too if I can find a way.

[Metallover]

omg I forgot zippies! I'll do those tomorrow...

IMO, I think Neu, FP, and Hyperion all use the same cell manufacturer. FP I think underrates their packs BIGTIME and/or use better cells from the factory/batch. Neu looks like they have the same prices as FP...and Hyperion is drastically cheaper (that's why I went with them) because IMO, they work with larger quantities? Largest of the three companies.

Or maybe Hyperion gets the lower grade cells, doubt it though, but if that were true, then we can only expect more insane levels of performance over the G3's, which I don't even know if it's possible.

Anyways, about the graph, I am pretty sure the 4200 G3's and the 3800 X30's are the same cell, the 3300 G3's and the 3350 X30's, the 2600 G3's and the 2450 X30's, etc... you have to go by weight, because they are merely rating the capacities and C ratings differently.

FP states 3.7v/cell @ 15C discharge.... my G3's are getting (if my Eagletree is to be believed) a little over 3.7v/cell at 6.5C....?

I am strongly considering buying a pair of X30's 3800mah packs soon, see how they compare to the G3's... I am guessing the X30's will be more at least the same, if not, more powerful, despite being rated lower across the board.

Me tired too, going to bed...

Ok, here is what I know...

As far as 25c cells go, fp, tp, polyrc, polyquest and hyperion all use enerland cells. Not anymore, as enerland does not sell to any of the mentioned as of a few months ago, but for all of the packs floating around it applies.

Now on to 30c stuff. The fp evo 30 is enerland, as are most of the rest of the 30c cells that have been sold for the past few years from tp, polyrc, polyquest, and hyperion. Pretty sure all of them, but definitely fp and polyquest are using the same 30c cells.

The fp eon line is different, non enerland stuff from what I have heard, but I have not touched those packs yet. Some people have had issues, and the line has been revamped at least once to my knowledge.

Hyperion G3 packs are the newest game in chinese lipos, not sure but I think that hyperion are the only ones who are using this cell ATM. Good stuff, and priced very well. These are getting very popular.

Tp have a 40c cell that is badass... Probably the best out there from what info I have seen. Not sure if anyone else is using that cell either. Pricey though, most likely sell very well to the plane guys and to people looking for max performance. Eating into fp business, but that is the nature of the game.

FP are supposedly having issues. The owe enerland money (rumored) and cannot work a deal with hyperion to get the G3 cells (also rumored). Plus they gave great planes (tower hobbies) exclusive reselling rights to the US, so alot of people who used to sell FP no long can (unless they go thru GP, and most appear to dislike that).

Maxamps have nice labels, and are waterproof. They also have a great advertising program, and lots of exposure. From what I have been told, by people with no experience, maxamps makes the best lipo ever, and, I quote "Me rustlar id toe sweet maxamps rulez n u r a douche". Not sure what that means but I am sure someone can translate...

I am not sure what has happened to polyrc, I have not looked into them for a while.

I will add more info as I get it...

Means he's a tool bag and he just classified you as a douche.

[BL_RV0]

James- any info on neu packs?

[Metallover]

Got the chinese lipos done. I'm mixing them into the main one and I have so many now I'll probably separate them by c rating.



Here is a newer chart with everything

[zeropointbug]

Linc, are you sure that FP and Hyp. are not that same cells? They both seem to advertise the same specs, 5C charge, 4x cycle life...

Even like I said in my last post, a few of the packs in the lineup seem to match up perfectly as far as weights go, and the difference in mah, could just be FP rating their packs conservatively?

Or maybe all the brands really are sourcing from different manufacturers, and they all just payed royalties to a patent owner for the same cell chemistry/manufacturing process?

BTW, I think Hyperion might be coming out with a 40 - 45C pack soon, as they still have their "VZ" line to fill in with G3 packs.

Also, TP 40C packs seem to be the same cells as G3's, only slightly more powerful... same discharge curve and everything, just slightly higher voltage under load. (proportional to 40C vs. 35C)


Only time will tell I guess.

[zeropointbug]

Shouldn't prices be added to the chart?

[Metallover]

I emailed flightpower asking about their packs and cells comparing to hyperion. I'll tell you if I hear back.

I don't think hyperion and flightpower have the same cells because: Flightpower EVO-X LITE advertizes 25/40c while Hyperion advertizes 25/45c. It could be a conservative rating, but I think on the cell is says the capacity and c rating so the company can't really change it. There is a possiblity and it would be really cool if they were the same, but I don't see it.

And prices, do you mean with every pack?

[nitrostarter]

I see names, I see capacities, I see C rating, but I don't see cell counts... And I'm not quite sure what this is going to be used for....

I could see if being useful to list every pack and all its specs and then you can use Excel's sort feature to find the right pack for you, or see whats available and compare.

EDIT: But that would require user's to exert an effort and think, or actually know how to use Excel and the sort feature....
