More bang for the buck.

that foil pouch with the masking tape looks curiously like the Cheer-Ocean cells ( or GEBattery .. stay away... far far away !!!!! )

They're both a pathetic (for lifepooo) 2C too, right?

 

[Ypedal]

The specs vary depending on who's writing the spec sheet !

These look to be German Gaia AKKU cells. See here for the full range: http://www.gaia-akku-online.de/ENG/...kte&-Token.Link=Link1&-Response=produkte.html

looks like Yesa are very keen to get our custom!

Lot's to get in couple months, everyone's talkin bout it.

Mr. Yesa battery,

sir, i went to you web site and when i click on purchase process, i get nothing. no information. While it's nice to see battery manufacturers take interest in ebikes, before promoting your company, it would be nice if you would have a product, good information, service and sale channels first. I don't think you're doing yourself a service replying to every thread and promoting something you don't have.

Don't have? The website may not be complete and fully functional but haven't they been selling the battery packs for months? I think their ebay store is one available source. There have been a couple of posts from members here in this forum that have purchased Yesa battery packs.

How does one tell the difference between a LiMN204 and a LIFEP04?

 

[Ypedal]

Peak charge voltage.

LiMn/Co = 4.2v fully chargeed

LiFe = 3.6 fully charged..

 

[Johnbear]

Thanks Ypedal, I appreciate the fast answer!

 

[Ypedal]

No prob.

To further that.

LiMn/Co will produce usable power at 4v

Life will drop down to 3.3v with any applied load. ( even 3v on cheaper/non A123 cells )

Giant, 60ah 2C li-ion cells for $520 each:

Great! I could equip my 48V e-max with them for only $7280 - not counting the BMS or charger!

 

[PJD]

OK, just $6916 with the quantity discount.

The point is, these still have to come down about 500% in price before they would be in my budget.

Check out the 40Ahr ones at Thunderstruck Motors. Closer to the right price range.

 

[Don Harmon]

Both LiMn Co & LiFePO provides a lower battery capacity when compared to LiCoO by about 20% Check the life cycles of the two chemistries also when comparing their differences.

Best,

Don

I can live with that...

 

[Don Harmon]

Most can, esp. when considering SAFETY & LIFECYCLE advantages of LiFePO4
