Puffed lipo by shorting?

[ReV:-O]

Hi guys,
I got a Neu 3s 5000mah lipo the other day. I was soldering deans to it and accidently touched the two wires for a split second. it made 3 sparks. Basically i am asking if i have ruined my new lipo. i think it has puffed a bit but it could be my imagination.

many thanks

very well could have damaged it. I don't have any first hand experience but from what I've seen on here a quick touch generally doesn't damage them.

If only for a split second you should be fine - Remember the spark you get when you first plug in a battery to an ESC - This is like a short as the Caps soak up the voltage very quickly.

I'd be suprised if you've puffed it - Check your voltage on all cells. Post up a picture...

But be careful! Not worth buring the house down...

Dupe post -

again sorry for the dupe post. you can delete the other one or wotever lol. i'll try and get a pic of it. i actually bought 2 of the same lipos, so this is why i think it is puffed because it feels squishy on top and the other one is solid.

What charger / balancer setup do you have - does it have built in volt meter? Do you use a lipo sack?

these are brand new batteries. never been charged or used. im new to electric so im not really sure what is considered a puffed lipo. ive taken some pics so i'll try and upload them

the 'puffed' one is on the left...

the caps soak up the voltage very quickly... but when i shorted it the cells must have absorbed the voltage

any thoughts? i know the pics arnt very clear. should i send it back to Neu? they sed i could, but im not sure if it is considered puffed. it just feels squidgy and the other one feels solid.

Send it back Rev:-o, I gather from your posts on Traxxas you dont have a esc, motor or truck yet, so you have some time. If Neu said they'ed take it back, send it back and consider it lesson learned

[ReV:-O]

i think i'll take your advice jayjay. the only thing is ive soldered deans to it. but if they ask i can just say the shop i bought it from did it for me. www.flydma.com do it anyways

It doesn't look puffed to me. I'd run it!

What are the voltages on each cell?

it should be fine , i have done the same thing

[hootie7159]

i've done the same as well when i soldered deans to my 2s 5000mah tp lipos....only a split second of sparks....i ran it til LVC, charged it back up and nothing was wrong with it you should be fine...
