Cells not holding voltage?

Cells not holding voltage?
I have a set of 11.1v 5250 lipos and 2 cells in one battery and 1 cell in the other will not hold 4.2 volts. It bounces around at 4.19 and 4.2. I have ran about 4 cycles of balancing the batteries after use and the problem is getting worse. Is there an issue with these batteries? My thunder power lipos have never done this but these have done it and getting worse since day one

We are closed today through Sunday for the 4th of July weekend. We will be back open on Monday the 6th.
Have a happy 4th of July.

125268 is my order number.
I was told by live chat that the cells bouncing around from 4.19 to 4.2 volts was not a problem? Is this true? I do not want to have to return these unless there is a problem, I paid for express shipping for a reason, I do not want to have to go with no truck for a week or more.
Another issue I have with these batteries is yesterday my truck was going pretty slow and seems like it was running on 7.4v batteries. Once I put the batteries on the charger they read 3.6v per cell. Should be plenty of power but once re charged they worked ok again. I have not got them down that low again but I am thinking that when they got that low they could not hold voltage under load, thus running very slow. I know this is not normal because my thunder power lipos do not and have not done this or have the charging issues these have been giving me.

As far as what the packs are doing during the run I really can't comment on that at this point because I have no idea what your using the packs in. A bit more info on your set-up is always helpful to us so we can better determine if there is inf act an issue. Also what are you using for a charger?

By bouncing around I mean I can sit there and watch the cells hit 4.2v then go right back to 4.19 in a second. It does this over and over and over and over. My other set of batteries I have does not do this, that is what made me think something may be wrong with them. I am using a Bantam BC6 is that matters at all.
I am using these in a Brushless E-Revo. All stock stuff on it. The batteries were supposed to me made for this truck.
Also, I think I was charged for the 3 year warranty? Are you able to check that for me? I read the thread about it being free.
Thanks.

Got it and yes you have the 3yr/300 cycle warranty on them. As far as the voltage from 4.19 to 4.20 that more than likely could be just your charger. If your really concerned check the cell voltages with a good quality volt meter, that'll give you more accurate readings. But as I said that little tiny bit of voltage difference isn't anything to be worried about. As for how you feel the packs are performing compared to packs that you have been running, well give the new packs a few runs. It's normal for Li-Po's to take around 6 cycles before they reach their full potential. If you feel you still have an issue feel free to contact [email protected] or call him at 1-888-654-4450 on Monday and he can help you out. Josh Handles the East coast RMA issues. But from what I'm hearing so far there appears to be nothing wrong at this point other than some minor concerns that I feel I have addressed fairly well at this point.
Have a good weekend.

I know I have the 3 year warranty, I am saying I am pretty sure I was charged for it when it is supposed to be FREE.
I know the voltage bouncing around is not my charger, as I stated before my other set of lipos do not do this on the same charger.
There is a battery specialist store by my house, I will see if they can do some tests on the batteries for me, I am more comfortable with a professional doing that than myself.

You were not charged for the warranty. If you would have been charged for it you would have paid $395.99 for the packs rather than the $362.99 that you did pay. So you did get the warranty for Free. And As is said there is no issue with that pack a cell having that little bit of a difference isn't going to nor will it make any difference at all. The pack is fine. But if you feel you need to have it checked out I would suggest you send it to us if your that concerned about it. We are more than happy to take a look at it.
Have a nice weekend, I'm off to the in laws for the 4th and will resume with this on Monday. Take care.

I am not saying the cell is hitting 4.19v and staying there. The charger charges it to 4.2v and the cells is just not holding it there.
Are you telling me this is normal of a Maxamps battery? Like I said, I have not had this problem with my thunder powers.

I understand what your saying 100% the cell is bouncing from 4.19 to 4.20 volts. That tiny little voltage difference isn't anything to worry about what so ever your making a big deal over nothing. You talking about a tenth of a volt. The minor fluctuation should even be worried about at this point and may very well go away after a few cycles. If it doesn't and it get worse say as I said .5 volts or more then you may have a bad cell. But until then if there isn't anything more than that there is nothing wrong with the pack. If you feel otherwise feel free to contact [email protected] or call the shop at 1-888-654-4450 and speak directly with him. He has the links to this thread and your others and is quite aware of what is going on and has come to the same agreement that you were told both here and our online support chat back on the 25th of June. I have those records as well. Your more than welcome to send the pack in but if we find nothing wrong other than what your posting nothing will be done. There simply is nothing wrong with the pack at this point.
Have a nice evening and feel free to contact us Tuesday seeing you didn't today.
