Bad Turnigy 3s ??

[Brushless55]

I bought 2 of these along with the 2s versions..

http://hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=9515

and they had awesome power in my MM and UL-1! I ran them once and put about 2200mah back into the packs.. Today I was testing the 8XL that went bad last week and I heard one of these packs make a slight snap sound, and lost all power?
I can smell a slight burnt smell coming from the pack, only ran about 30sec at slow speed nothing got hot, and now nothing from the pack.
I used a voltage checker and I can get 4.14v from one a two cells but nothing on the third?
Help, can this pack be sent back or should I cut open the end and see if I can fix it?

Thanks

Not sure how you could fix it? I have the same packs and I love them! What was wrong with the 8xl?How many volts are you running through an 8xl? On which boat was it and what prop?

I was running it on 4s then tried 5s with a CF42 for only a couple minutes, in my Mean Machine... ran awesome on 5s and did not get very hot

Sounds like the tag that comes out of each cell - One of these could have broken and will cause a open circuit.

[Brushless55]

would it just be faster to fix it than try and return the battery for a different one?

You didn't state how long you have had these? Are they still under warranty? Do not try to fix as if you open them you will void any possible warranty . Contact Hobby City and see if they may be exchanged. If not then you can try to open and possibly fix them like Team said a tab may have burnt out. That is what I would do.

Good luck!

I would check with Hobby City to see what their take would be on the pack. I love my Turnigy 2s1p 5000mah packs. I have over forty cycles on one pair and still going strong.
It does sound like one of the tabs is broken. My only worry would be what caused it.....since you smelled some heat. It's not a hard fix, but it may puff the next time you use it if you fix the tab and carry on.....the smell is what tips it for me.

If I don't hear from them soon, I'm going to cut into the lipo and fix the issue..
I hope a simple solder job will get it going.

You cant solder the tabs if it is that that broke. They are aluminum and you need very special solder called aluminum paste. Send it back th hc. They are under warranty

i also have 2 for my intruder s and love them and have had no problems at all

The question is what was wrong with the 8XL motor. You may have put an undue load on your whole system. I am interested as to how Hobby City respond, keep us up to date.

Still not sure what happend to my 8XL?
When I ran my packs they only got to 90* and only took out about 1700mah.
Charged just fine, and put these batteries upto my MMM brushless revo, hooked up my 8XL to the esc without load and ran the motor for about 30 seconds up and down, the motor was getting hot, esc very cool and batteries very cool, then I heard a slight snap sound come from the one pack and lost volts from it..
Hooked up other packs to this and the esc and motor still working..
HC has not gotten back with me about any warranty yet..

Yes this is what Im thinking too, id be inspecting the 8XL to make sure theres not a rogue winding in there touching the rotor or something else bung.

When you say the 8xl went bad do you mean :

a. it dropped out of school and started smoking crack
b. it got its cousin pregnant
c. it spun the magnets
d.all of the above
