I never heard of them (not that that means anything). This page:
http://whois.domaintools.com/goasisenergy.com
shows info about their website registration indicating it's registered by a company "Keming Li" in California, even though the company itself is supposedly in Illinois.

Also, this image:

of their company's buildings (presumably) appears to be a shrunk version of one labelled with ideographic characters like those of a few east-Asian languages, like Chinese. Can't figure out why that would be the case; it seems odd.

Also, the (only) picture of the packs they sell on their site itself shows a label on them for KELING BATTERY, presumably the actual (Chinese?) manufacturer/assembler, so this company is most likely just a reseller like BMSBattery and many others. Hopefully they actually stock the items they sell, unlike at least some of those companies (the ones that take forever to ship anything and dont' respond to inquiries after sale).

That same pic is also used on the Ebay item, and so is probably not the actual item in question. So who knows what the actual thing is gonna look like. ;)

The ebay description gives "about" measurements in inches, but the PDFs on their site give exact measurements in millimeters.
 
Thanks AW, sounds like it's a crap shoot, customer found this company on ebay, and wanted to know if anyone here had first hand experience.

Hopefully it turns out to be a good company, I think he is wanting to buy from a local company for better support, hopefully they have more than a couple batteries in the US, good points to ponder. :)
 
I'd want to at least know if it's round cells or pouches. By weight, it reeks of a round cell pack.

Edit, looks like it's pouch cells.
 
So dlg quoted me $350 for 16s5p pack, bms, and charger made from these 15c cells http://www.alibaba.com/product-gs/435831668/High_Rate_LiFe_PO4_Lithium_Li.html

Someone here really needs to try them! (johnholmes actually tested the individual cells, and yes they are 15c)
 
Thanks all for the in-put!

My customer unfortunately, did not go with my advice and just get a ping for $80 more, and ordered this battery, despite all it's apparent short-comings and poorly labeled listing, I hope it works out for him.

If it's only rated for 20A continuous, I fear that the controller he has (30A) will make short work of this battery, and if it is a round cell pack as you suspect DM, I'm sure he could have bought similar quality for what, $500 less?

I really hope that they stand by their warranty, he is a "brick and mortar" kind of buyer, and didn't feel comfortable with ping thinking he would not have a way to contact a live person on the phone if he had problems (he hates computers, and is having a family member buy it for him with paypal) and thought this company would be a better risk.

I hope we are all proven wrong and that it works well enough!

I have been particularly under the weather as of late or I would have checked back sooner, take care all, and enjoy the spring weather!

Thanks again for your wise advice!
 
Pretty likely, or maybe it works fine, but kills a cell group fast. Hopefully the battery is fine, and just has a very conservative spec sheet.

Edit, I have been confusing this battery with a 48v 15 ah battery, looking closer, I see my comments so far have been full o crap.
 
Yeah, my fear is that he will have trouble and then his opinion will be "E-bikes suck!" or something. Either way, thanks for seeing what I missed and bringing it to my attention. :)
 
Well, we will have some information on this battery soon, he should have it in a day or two, but in their defense, they do seem to be relatively conservative on the rating of the said battery, only recommended for 800W E-Bike, and would recommend the 30AH for 1400W (this is the max he could pull however, but should not be continuous by any means, just burst at 1400W)

I'm not seeing the inconsistency in the description Y-Pedal?

Here is what is in the E-bay add, and this information has been confirmed by the company directly:

Rated Discharging Amperage: 20 Amps

Max. Continuous Discharging Amperage: 40 Amps

Max. Discharging Current: 60 Amps

And they do have a 12mon. warranty, so it will really come down to how the stand behind their product, and if it delivers, ping may have a competitor, I for one welcome them if their battery performs as described.

This customer of mine says he wants to pedal first too and take really short trips to the corner store (less than 5 miles) so maybe it will be ok even if it turns out to be less potent.

I always try to get more battery that I need, hopefully this will pan out for him.
 
Good news, so far, when bench tested at a few battery shops (battery factory etc.) the battery puts out the amps as advertised, no specifics ( I don't know what the voltage sag was under load) but according to two local battery shops it's the real deal specs wise.

Now only time will tell on durability. :wink:
 
I just saw this battery in person, and I must say, I am very impressed!

The battery lacks all the cheapo "duct tape" of some of the others, has nice white with blue outer shrink wrap, and came with a very high quality looking charger!

The charger is the most impressive looking, as it is metal with a very good design from the looks of it, built in fuse, 4A, but hey it's free with the battery, has a separate plug-in for the charger so you could just leave the battery installed, and other than the cheesy 3 prong "microphone" power connector, I wouldn't change a thing on it if it were mine.

Again, time will tell with the durability, but so far, this looks to be a good battery.

P.S. also wanted to mention the packaging was first rate! not the cheap stuff, but the white close cell packing material custom cut to hold the battery, and it has a 1 year warranty.

I read that wrong too until i saw the ebay description :p
 
Sounds like a decent pack then. Can you tell if it's round cell or pouch? If it's pouch cells, I don't see why it would weigh 26 pounds. 21-22 would be more like it. What does it actually weigh? Perhaps 26 pounds is a shipping weight that includes the box?

20 ah size should be able to handle a 30 amp rate, if the bms doesn't pop till 40 amps is drawn continuous. I think I was thinking a 15 ah battery when I made the first comments.
 
Looking at the same sellers store, he lists a 48v 15 ah battery. That ones dimensional size and weight is much closer to what you get from ping. So it looks like we have a seller in the USA, who has a battery very very similar to a ping, at better prices. Somewhere around 50-70 bucks cheaper than I paid for my 48v 15 ah ping for his 48v 15 ah lifepo4.

I would think though, that if you had a problem the CS response from Pingbattery might be faster. This guy may not have spare bms in his stock. However, if you did need to ship one back, MUCH better than a hong kong ship.
 
Looking some more, this sellers prices for 36v 20 ah is much higher than his price for 48v 15 ah. both packs have the same number of cells. Hmmm. So each auction will have to be judged individually, to see if it's a good price or not.

Still good to know this seller exists.
 
Hi everyone. This is my first post so I hope you don't think I'm some shill for keling.inc. I'm looking to build a 9 Continent rear hub kit from Grin Cyclery, but I still need a battery and I don't have enough experience yet to build my own.

Just wondering if anyone else has had dealings with this company. I like the fact that they are based out of Illinois (just in case of legal dispute). And their prices are over $100 less than Ping batteries.

I called them up and got a asian accented woman on the phone. Not very professional, just a "Hello?" I talked with her a bit and found out that Keling Inc. has been around for 7 years, but the battery business is new "due to demand". They resell the batteries from China, but they do have some of the batteries in stock in Illinois. I couldn't get any specifics about the Warrenty from her accept that they will honor it. She said I would have to email support.

Anyway, really enjoy the Forum and have learned a lot in a short time. I can't wait to be able to bicycle to and from work without breaking a sweat!

To me, if a rep that answers the main phone of a company can't help with explaining their (non-technical) details of their products, that spells probable disaster later on. If they don't know answers to something, they ought to immediately get you to the person that can. If you *have* to email someone else just to find out answers you need before you buy, instead of asking on the phone just before you make the order, then that's a bad sign. Nothing wrong with *being able to* email for those, as I personally prefer it to phones, but *having* to do it when they already have you on the phone isn't good.
 
Sounds like they just resell stuff. Just stuff, in general.. no focused specialty.. and they don't seem too knowledgeable about their product.

Which is almost always a bad thing.

I went on their site, they try to make it look like they are a battery manufacturer but you know they aren't.
