Yesa vs Ping packs

[EcoForumZ]

I have seen a lot of posts about the yesa and ping packs and wanted to see what everybodies thoughts are on them. I am referring to the LiFePO4 packs sold on ebay. I know many people love the ping packs and I just wanted to know how the yesa packs stack up.

The Yesa lifePO4 36v 10ah pack has 12 cells in series, 10Ah each, at 3.2V. Would anybody know what the ping packs have so we can compare?

IIRC, his packs are made of 5Ah 3.3V cells.

In comparing between his and the YESAs, the YESAs win out. But, naturally, you're going to pay a lot more for it. Ping's packs are fine in most situations, though.

I read a couple people mention about Pings batteries heating up. I don't think LIFPO4 batteries are supposted to heat up, mine certainly don't, and i ride them long and hard.
Heat will degrade batteries, that's for sure. But these might be isolated cases only.

I have low rated 24ah 2C cells that get warm at 1C and HOT at 2 C...

some 12ah 5C cells that deliver 4C and get slightly warm..

I don't " yet " have a controller that allows over 40 amps.. but with any luck that won't be for much longer !! hehe

The Yesa website shows the maximum discharge current as 25 amps for the 36v 10ah pack. Depending on how many amps your controller/motor need, the 10ah Yesa pack might not be enough for you. I know some people who bought the 10ah Ping pack found that it cut out on them and they really should have bought the 15 or 20ah packs. I think most folks who bought the 20ah pack seem to be satisfied with it. As I recall, Ping's packs are something like 3 C.

I didn't know about Ping packs when I bought my 24V10Ah pack from Yesa.

In my experience yesa's quality is good, but I'd buy more watt-hours for the same price if I could.

My ping only gets hot because I climb a hill for one hour non stop in the desert where 85 farenheight is considered a very cool day. My lead batteries got hot under the same conditions. My brushed hub gets nice and toasty. Other batteries got hot from shorts caused by batteries rubbing metal while riding. My ping 36 volt has 12 cells, each cell has several pouches, each pouch being 5 ah. The big advantage to yesa I have heard, is being able to parralell or series connect them. I just liked the price of the ping, and would need two 10 ah yesas to go as far as I need to uphill. At this point in the market the best battery is the one you can get your greedy little hands on.

Hi,
among not much I arrive the YESA of missbattery and I can finally put them in comparison with those of Ping.
