Also, if you post a picture of the half pack with puffed cell and a picture of the BMS, maybe guys here or I can tell you what caused the problem and give you some advices.

This was my mistake to ship the package to your PayPal address. Not by any of our staff, but by me. I'm very sorry for this mistake. We will ship a new cell group (6x cells) and parts to you. I know that might not be enough to make you calm down soon, since I haven't got your response on the...

BTW, they should be KP series chargers, not EP, as you can see in the printed user guide. Ping

Hi all, Long time no see. Recently, we're testing EP series chargers and found a problem when charging LiFePO4 battery packs. We're glad to share it with you here. The EP series chargers are originally designed for Lipo battery packs. So, it has a function of Power lock - when battery pack...

Hi Bill, I sent two emails to your two address last week. And I had replied the first email. Please check your spam folder it there is. It seems to be an imbalance problem caused by the low voltage output from the charger. Its voltage should be 60v-61v. I have re-sent those emails to you via...

Yes, resolved. Now we ship batteries with EMS. UPS really sucks. There must be a guy or a team in KY who don't know anything about Lithium batteries and don't want to know, although we did provide all information. They held many packages to east coast and we had to full refund to those...

Hi, From next month, our 48v charger will be upgraded to smaller and more quiet, just like a power supply for laptop computer. However, there will be still a fan. Of course, we will sell it on our coming web store. Ping

Dogman, If you take a look at Cammy's listings carefully, you will find she's using at least 2 kind of cells with different density and pricing. BTW, 300x150x110mm for 48v20ah is ultimate density of LiFePO4. It's hard to make it. Also, please give me a chance for advertisement. Almost all her...

Because I reported to ebay with compelling evidence that she's using her other accounts to lift the price. Finally, ebay warned her and she cannot bid up the price by herself. So, buy it now noly now. Or, her auctions will finish at very low prices. I didn't want to do this although I already...

Vaporthug, good post. Please go ahead. Also, I need to explain something that could be misunderstood from your roommate. 1) We cannot ship batteries to the US in only 1 day. 2) We never sent second chance offer in the past 6 months. But there's someone else that is using her other accounts to...

Hi everyone, Thanks you so much for your suggestions and support. I cannot read every posts now because we're busy preparing for our own web store. Nevertheless, malicious bidders came again today. I think I know who she/he is from the beginning, but have no proof yet. But it's not important...

Today we have met malicious bids on all our ebay items. This kind of things have never happened in the past months although we did have many competiors. So, finally, we have reviewed all the completed ebay item completed in the past 7 days from a seller coming recently. And find there're many...

I have learned ebay rules and cancelled malicious bids. perspiring...

One hour ago, all our ebay listings have been bid to a very high price by zero feedback ebayers registered just today. :evil:

Cammy, It seems your "sorry" was not said to me, but to all the others who could be your potential customers. However, I think you'd better apologize to me first. Please don't explain what "ping" means. eBay.com is a US website and we are both Chinese. Even if "ping" means "cheap", why didn't...
