G-Power in china

[randomlight]

Has anyone bought anything from G-Power in china.The prices are great, they have a phone number so you can discuss your purchase,and their "about us" on their webpage says that they supply walmart superstores with their patented hub motors for their shopping carts.(possibly not here today gone tommorow type of supplier).Im looking to buy a 36v 10ah battery pack with the rear locking carrier and they charge only 268.00 (includes charger)

I'd be very interested in hearing about this too if anyone has had any experience with them. They are offering 20ah prismatic packs for $31.00 and have Headway 16ah cells for $25.80, those seem like really good prices to me from what I've seen so far.

You get what you pay for.

From what I have read on this board anything coming directly from China is risky.

I've also read of many people being quite happy with orders originating in China. I also don't believe that the more expensive product is always superior to the lower priced options.

I agree with Jason. Better to spend a bit more on a quality pack from a company that is known here and actually have something in the way of warranty rather than 'well, you can ship it back to China for $200' packs that aren't tested.

If you have been here long enough and keep an eye on the new threads, you don't often see any long term reports on these ultra cheap lithium packs.. but you do see a lot of threads from people who are having problems with them from the get go.

Not necessarily interested in the pre-built packs but rather the lose cells, while the prismatic cells are probably not worth considering when a comparable product of known quality is on the order of twice the price. The Headway cells however are cheaper than I've seen elsewhere but not overly so as to raise suspicion I feel. I recall a recent thread about http://www.coddpower.com, also a new company to this forum, however it has come to light that others here have had successful dealings with them, this does not prove that they are a completely trustworthy source of products but it does bode well for others looking for new retailers. I'm sure Ping has earned his reputation but at one time he was also an unknown, and it took a few guinea pigs along the way to validate his services.

All that being said I'm probably just as skeptical as you are, even so I'm still hoping to get the most bang for my buck without flushing money down the dumper in the process. If I was a little more technically advanced and better equipped in the areas of testing and evaluating I'd be up for a run as a guinea pig with this retailer. I'm just interested in options and fully understand that many times if it sounds too good to be true it probably is.

Anyhoo... I'd still be interested in knowing if anyone here has had any dealings with G-Power.

Regards
Richard

If you're going to take the gamble, please report back when you get them running, and a bit later down the road.

Many people take the gamble on unknown Chinese companies, and we either hear that they got sold some crap.. or don't hear back from them again period.

I'll stop lecturing now Good luck to you Richard.

Nope, I don't see a lecture at all, just sound advice.

I just can't help but wonder if every Chinese retailer with only one or two exceptions is unaware of the expectations of customers in other countries like the US and Canada? Looking at the G Power web site I'd have to say that they are obviously targeting sales outside of China, and they have to understand that the nature of this market is one of word of mouth.

bmsbattery.com has 10ah headway cells $1 cheaper than ebike-bmsbattery.com

I made an order from G-Power: e bike kit: hub motor 36V350W front wheel without spokes and rim, controller 36V350W, throttle and breaks;
Total cost with shipping 170$;
The parcel arrived Friday 17 June; I was Saturday to a bike shop to mount the motor with spokes and rim and yesterday I took the wheel;
I came home and start to assemble the motor on the bike and made the connections; everything works good and today I will finish the work;

At G-Power there is a nice girl, Julia; she is very receptive and try to do the best;

Yes I recently bought a hub motor and two batterys from G-power . The power of the motor was impressive ! but its battery has problems at the moment . Julia is helping me out with the problem , she knows her stuff , but dont expect a fast reply .
The outher battery works well on my outher bike for distance , but will cut out if I use full throttle up steep hills for too long . :|

Prices will come down. Manufacturers are working to build successful businesses in China. It's the kind of capitalism we used to have, but for some odd reason their government clings to some notion that they are communists when they aren't even close.

Regardless, it's a gamble.

Like others said, I'd rather go with what many before me have recommended. I'll be getting a new battery soon and it will either be Ping or Cellman (or possibly from something domestic if the prices go down a bit).


Also, keep in mind that China has a mainland, and it's different from Hong Kong or Taiwan.

 

[Brewster .]

Yes , prices need to come down . The prices we pay for any high tech battery are hard to ecxept even if they are trouble free .
I hope I can get some kind of warranty on mine , or at least the parts to fix it at discounted price .

I have the same battery as in the first post. I'm pretty sure that the BMS is set to 20 amps. When I use it on a bike with 20 amp controller, I have no problems, but I tried it with my GNG kit at 22 amps, and it keeps cutting out. The cells seem to be capable of giving more because I don't see significant voltage sag.

What is the maximum current of your controller and which battery do you have that's cutting out?

 

[whatever]

I was looking at g-power website, in the controller section they have a programmable controller, very interesting, no price given
but the specs say its 36v, dont think i've seen a cheap ( assuming cheap)programmable controller ( apart from the xie chengs)

OK , The 500w motor i am running will pull 25-30 amps and the controller will take it , no probs . The battery is a 24v 20ah item ,
I also have a 24v 12ah battery , that will go hard until its power starts to get a bit low , then it will cut out . I use this one for hill climbs ,and swich to the big battery for cruising .

 

[Brewster .]

The battery that cuts out on full power with a 500w motor is a 24v,20ah item in an alloy case and came with a rack .
I wish it had an adjustable BMS more so than a programable controller .

To be fair I have to say I now had a positive experience with G-Power. The thumb throttle broke on my bike (9C motor running since 4 years, 12000 km) so I ordered one from them since their offer was way cheaper than any other and shipping cost was reasonable, 12.2 USD shipping included. The item arrived but it looked as not new, and indeed the handle gets stuck when released, quite dangerous on an ebike. Plus the throttle stopped working on the first rainy day. I got upset wrote them politely plus started a paypal claim.
They responded immediately, claiming that they ship working tested items blablabla. But they posted a replacement item with faster shipping in order to make sure the item arrives before I have to escalate the issue.
And the item indeed arrived, they even included a small nice present in the package.

I agree it is a risk to buy directly from China and also I was sort of lucky to discover the problem in time to be able to start a paypal claim. Batteries I would definitely not buy directly from China since shipping has high cost and long-term functioning of a battery is really based on trust, i.e. seller actually sends a brand new, tested item.
