BEWARE of HAIYIN poor customer support, poor show from the company

I have other important things to do than arguing with their customer support for so long.

Chapter closed. Well that's good. You claim Haiyin has poor customer service, sold
you many bad packs,and won't help you.

You need to show us, Helifreaks, some real proof that these are all bad packs. A $9 blinky tester
does not count. Have you cycled and balanced the packs as you were told to, by more than one source?

They have more than once tried to make this right. But you have more important things to do. Not looking good on your part Hellydoc.

Wait wait.....


Dear all,

I have few questions to Haiyin...

I do accept that icharger and the tester used may be cheap. But, that doesnt mean they are all junk.

But, can you please publish the voltage data when the batteries left the ware house...I mean the actual archived data (Must have been recorded)...It will be unique for every pack with a different bar code...Are the instruments you used calibrated? Of course, yes will be the answer. But, was it a partial calibration or full calibration? When were they last calibrated? If the calibration is reaching its end, then there is a chance of error creeping in...( I gladly accept that i used icharger and a cheap charger, But can you please answer all the questions)

Also, how are the Internal Quality Standard maintained in your lab? What was the CV when the packs were standardized? Also, Has the lab been enrolled in an External Quality Assurance System? If yes, what was the Standard Deviation of the same batch to which these packs belong?

Thanx Trev: I will definitely buy one in future

@ Greg: I am again going to cycle the defective packs 5 times each. And, make a video and put the results in front of everyone.

If the packs balance out using the same cheap icharger and tester. Then, what will be the answer from Haiyin?

If the cheap volt watch shows a defect again, i will also compare the same cheap volt watch to a a good volt watch inbuilt in a charger like Bantam or Hyperion...If there is a difference and cheap volt watch shows an error,I will APOLOGISE right here to ERIC.

And, if the results are the same in both volt watch, Then Haiyin needs to answer.


Also, let me elaborate: I ordered 15 packs. Eight were 3s and balanced right out of the box and other seven were 6s packs. In these 6 showed a voltage error.Eric told me to cycle which i did but got the same result. I Also, never wanted to raise a finger on a big company like Haiyin but the problem triggered when i was told to send the 2 packs at my own expenses and secondly, the statement "we are not worried". So, i had to post here...

They fail to understand that sending two packs from India to China or Taiwan with a wight above a kg cost 60 dollars here. It may me just 60 $ for them but here it costs rs 3300..U c the economies work different. Also, even if the packs came out defective and they send me a replacement packs, who is responsible for all the customs duty of 30 to 40%? I am not asking Haiyin to pay that for me. But, the whole business proposal for which i ordered these packs as a sample goes in geopardy due to lack of profit.

BTW, the iCharger is better quality than the checker. I would not put them in the same class. Before cycling the packs again, I would put the iCharger into monitor mode and check the cell readings (without charging, or cycling). Compare the iCharger's voltage display to the cell checkers.

No worries, will do that also.

I haven't reviewed the whole thread, but when you charge is it a balance charge? It has probably been mentioned before but I would think a balance charge is the way to go as each cell is managed during the charge and discharge for that mater.

[hellydoctor]

Hi Ronj,

Yepp its always balance charging that i do...I am cycling the pack five times more, taking time but will clear all the things..

[Kneedragger75]

Have not heard from OP. This thread was to warn us of Haiyin's poor customer
service.

Well, what is the verdict Hellydoctor?

[John Cook]

I've known of several hyperion chargers that allowed some cells to over charge and in short order kill the pack.

If the hyperion charger is overcharging that cell, this is what you will get. Reading a cell on another device is going to show a high voltage. You need to discharge the pack, then charge to a storage level on the icharger. Then read on other devices and see where they read. Are they all in balance? IF not which cells? Is that accurate? Other devices showing same cell example cell 4 high at similar levels says it's indeed a cell 4 being high. Now is it high due to bad pack or bad charger? Then you need to for sure get pack in balance somehow. IF it was bad charger how do we know? We have to make sure the cells are all at a nominal-storage charge ie 3.7-3.85v in that range will do. Then if we confirm they are all in balance, then you charge pack on charger keeping an eye on the balance screen to make sure each cell does not pass 4.25v peak during charge. IF it does, remove pack. Check against other devices to read cell voltages. Is that one cell still consistently high? It would be unlikely the pack is bad with high voltage in one cell. I have not heard of this being an issue with Li Po batteries. Only times I've heard of this has been due to bad charger.

However, if the pack won't come into balance or stay in balance then that's a pack issue. This cannot be determined if you only have one charger though. You need to have known good equiptment to help diagnos bad packs.

sounds like the problem here is the shipping cost,if u buy something form ur local
store get home and find it bad do they pay for ur gas to get it back to them NO
now why are u buying from them to start with(u think u can save money right)
well that is part of the risk for saving the money when u buy from them.I dont know of
any place in the USA that would not want u to do the samething.so do what they requre or just shut up.

[Kneedragger75]

The OP has shut up. Have not heard from him since he was going to balance and cycle
all those defective packs.

Could be they were all OK and he just can't be bothered to post about it.

This kind of thread happens all the time. People rant and rave as soon as an
injustice is perceived, then when things work out, we don't hear a word.

Seems fair.

[HAIYIN]

Have not heard back either

[Kneedragger75]

Since we have not heard from OP and neither has Haiyin, then I will assume the
packs balanced and OP is just too busy to post his mistakes.

These threads really tick me off. If you make a claim on a public forum, back it up.

As far as I can see this is an endorsement for Haiyin.

Agreed, they did more than I would have expected.

Dear fellow fliers.

I have cycled the pack 8 times using Bantam 8 DCP and now checked the voltage with the same charger. The volt watch is showing an error as usual but the packs are balanced as shown by bantam.

I hereby apologize to Eric and Haiyin. I did what seemed to be right at that point of time. Now, i am wrong so i apologize to them.

But, they shouldnt have said to me that do whatever u feel is ok, we dont worry. I still feel that it was wrong on their part as nobody wants to come in open forum like this.

Regards

[HAIYIN]

Hi Doc,
Apology Accepted
NEXT...
Best regards
Eric

[hellydoctor]

NEXT....??

More batteries to be bought from Haiyin...

Doc

[HAIYIN]

"NEXT" is a slang for meaning,,. "moving on to the next issue, this one is behind us" it is not a question! Thanks for the post though

I disagree with the negative posts in the forum.
We live in Belgium and my son is flying 3D in Belgian heli competition.
We ordered already a lot of Haiyin batteries. Especially the 5 cells.
We never had one problem.
The quality of the lipo’s is great.
We have one with about 65 cycles and the voltage difference is minor.

Kind regards
Bernard

[w4llet]

never trust those cheap lipo voltage checkers. i have tons here and none of them give same results. to be honest none of them give same voltage each cycle it checks. i trust only my icharger battery monitor. it is the only one i have that match a fluke multimeter.

Seems like the return shipping charge is what really ticked you off. Maybe your thinking about receiving a wrong item in which case the company SHOULD cover the shipping charge back to them. In this case of a possible problem part, almost all companies require you to pay the return shipping cost.

Bought my first heli from, guess who, Xheli, and when reading their csr thread, everyday someone was po'd cause they had to pay for the return - no one could get through to them - lol

Hope you have this figured out now.

PS - Amazon is the exception to this policy as well as companies that charge double the going price because, well, they can afford to.
