    Have you tried plugging it in to something? does your volt meter work on the battery beside it?

    I would check the voltage on each contact on the balance plug, this would show if any cell is faulty

    [13:54:44] Randell: Welcome to HobbyKing! I'm Randell.I hope you're doing good!.How can I help you today?
    [13:55:01] Yasin DURAN: Hello
    [13:55:25] Randell: Hello Yasin.
    [13:55:51] Yasin DURAN: I have open claim case
    [13:56:15] Yasin DURAN: Is there any progress on the case?
    [13:56:24] Yasin DURAN: Claim #100027557
    [13:56:28] Randell: May I have the Claim no. Please?
    [13:56:45] Yasin DURAN: Claim ID: 100027557 Order ID: 101010496 Date Requested: 2/9/2018
    [13:58:10] Randell: Upon checking it seems that you claim has been rejected.
    [13:58:26] Randell: And This would be the message that is in your claim.
    [13:58:31] Randell: Service Centers don’t accept crash, damaged parts of the items due to misuse, and items that have been modified. ** accepts no responsibility for the improper installation and use of purchased products.-The warranty period for all types of batteries is within 30 days, 1 year for other products such as internal parts (ESC, motor, servo, etc.) and RC items (plane, helicopter, boat and car). The warranty period is effective unless otherwise stated on the product listing. All relevant information must be indicated on the RMA application form.
    [14:08:48] Randell: Are we still connected?
    [14:09:10] Yasin DURAN: I've used it for nearly 40 days without any issue. it there was any misinstallation it would affect other 3 too whitch I purchased them from u simultaneously. And plz notice that it was working fine but one of them crashed suddenly.
    [14:10:15] Yasin DURAN: I'm your customer since 4-5 years ago and u can check my order history
    [14:10:30] Yasin DURAN: yes
    [14:12:02] Yasin DURAN: besides these 4 battaries. i got another 2 brfore snd i'm still using them without any issue except the faulty one
    [14:12:58] Randell: We understand you frustrations Yasin. But since the item was modified we do not have any liabilities on this one. That is why we are suggesting to the item checked before modifying it.
    [14:13:57] Yasin DURAN: why are u convinced that it has been modified?
    [14:14:19] Yasin DURAN: I've not modified any parts of it at all
    [14:16:15] Randell: That is what came up on the results of the evaluation of our Warranty team.
    [14:17:42] Yasin DURAN: what were their evaluation result?
    [14:20:43] Randell: That the item has been modified.
    [14:24:47] Yasin DURAN: would i ask to provide a little bit more information about their result? because i dont understand how they concolude that result while i did not change or modifiy it at all?
    [14:26:47] Randell: It would be because the battery has an included connector and changing the connector counts as modification. In item such as this We suggest to seek advise from Our product specialist first before modifying the item.
    [14:30:13] Yasin DURAN: after failure, i tested it with another connector which was working to see if it work. but even with a good connector it didn't work. and as u can see the item is a packed thing and it is not possible to do any modification on it. the only possible act is connecting the connector and use.
    [14:31:05] Yasin DURAN: without any clue, how they convinced that I modified connector? it's unacceptible
    [14:31:25] Randell: As you have said, you have tested it with another Connector that counts as modification. that is why your claim was rejected.
    [14:32:13] Yasin DURAN:

    [14:32:53] Yasin DURAN: i even filmed the exact situtiation and sent you
    [14:35:35] Yasin DURAN: it's really unacceptile to concolude it as modification. If u put that in modification category, then using the batteries with my car should considered as modification too, because I'm using them on a different car than yours!!!
    [14:36:24] Yasin DURAN: even using the batteries on another country or weather condition could be considered modification!!
    [14:38:26] Yasin DURAN: I didn't attached any other connector to it except testing it with the same exact connector (which is simply a conducting cable) that I got all of them from u. and even i did it after the battery stoped working
    [14:40:20] Yasin DURAN: if the item was modifiable I would accept your possible concolution. but it is packed one without any ability to be modified!
    [14:41:50] Randell: We understand your frustrations Yasin. We apologize for the inconvenience. And the best possible way I can do about this concern would be to forward this to our Management to have this reviewed. However there are no guarantees that it will be approve.
    [14:42:57] Yasin DURAN: ok. how can i contact with mgmt team?
    [14:44:04] Randell: We will send this to our management and it will be reviewed. To have any possible updates you can contact us back.
