My luck gets worste...
 

My luck just sucks..

just ran my truck, came back to throw the batt on the charger, one cell is at 2.86v.... someone tell me i didnt kill it

the pack is a zippy 5s 4000mah pack, someone tell me that they have gone further and survived :cry:

all the cells are at 3.65v now.

am i cursed?

1. Original 8xl-fried
2. 2 spur gears stripped
3. slipper nut wont stay on
4. lost the front center drive cup and dovgbone
5. lost my 16t pinion in the grass
6. this...

You need to buy a good set of hex drivers, and a bottle of thread lock...

What charger and balancer do you have? I would charge the battery slowly, like 1.5amps and balance it at the same time. The go easy on the next few runs and do not drain it all the way. If it did not puff it should be fine...

NO.. it not just you!! I lost tons of money when that happened to both of my PQ 30C lipo's dropped too.. I feel your pain BB..

Sorry for your loss.

i do, i have t-handles..
and the pack is on at 1.6a already
i loctited EVERYTHING... thiis truck is cused..

charger is imax b5 charger/balancer

did it blow up? hope not. how the heck did it happen?

nope, i ran it down, then threw it on the charger and almost soiled myself when i saw 2.86 v

i just checked it all the cells are holding 3.9v

hmmm thats weird, if it balanced out and is not puffy, then i think you will be ok

*sigh of relief"

Notice he said "I think". Nothing is certain; only time will tell. I would do a couple gently cycles keeping an eye on any imbalance before going balls to the wall again...

yea.. ill probably drive around my basement tomorow since it is raining cats dogs and turkeys. lol

did you do as sugested and only run the lipo %50 down the first 5-10 charges to "break it in" i always have done this. I have only lost one pack and it was my 1/18 scale maxmaps pack so go figure.

yes, did do break in.

Ugh... That's why I can't bear to buy expensive lipos. If I killed one I couldn't get over it.

I'd do as said and just run it. I've overdischarged a few and they ended up being ok. Just don't make it a habit. You may lose some life, but eh, it happens.

2.86v is fine on its own, I think the specs say don't take then under 2.75vpc.

That said, it probably did drop below 2.75 if you were running it in its current state, and gave it a bit of WOT.

If its not puffy don't stress too hard. I haven't personally had a lot of experience with Zippy packs, but my brother has about 10 of them and most of them stay all within 0.1V, a few packs have a single cell that can strays out up to 0.5-1V though.

Crank up your LVC to 3.2 or 3.3 or something should help keep a a bit of a safety margin too.

i just checked the pack, all cell held voltage over night, all at 3.87-the cell in question was at 3.86, so im happy :D
