So i have 2 fantom batteries and i love the performance out of them, i just recently bought another fantom that is a 6500mAh and 60c-120c burst.
i have been charging the pack at 6500mAh and 5A.
I ran this pack through my SCTE probally 5 times and i noticed yesterday after i took the pack out of my truck it was puffed a little bit? I dont think it should be puffing at all. Im using it to power a Rx8 and 4600 pro4 motor.

after about 10 min the pack went back to normall for the most part and was pretty warm after i pulled it out.

$120 battery should not already be puffing.. any help?

Mostly every battery gets warm and expands when you put a heavy load on the battery

ok, so you're saying this isnt hurting anything? that they all do this? my other fantom didnt do this when i had it in the truck..

I ran 3 different fantom/revtech orange case packs than they all puffed within 20cycles one dropped a cell within 10 cycles . I will never use a orange pack again .
Orange packs r only good (for me) on July forth . charge it , shoot it , watch the pretty lights ... Most expensive light/smoke show of the day..

How low did you run it to, what is your Low Voltage Cutoff setting? A heavy load and running the lipo down too low is very hard on it. Much better to stop slightly earlier.

Yeah i was thinking this could be the problem as well. i ran it to lipo cut off. wich i dont do, but the one time i did this is what happend. just going to have to go back to running about 5-6 min..

yeah its the "killer volts" pack, biggest piece of S*$t i ever seen. can't believe i would drop 120 bones on a pack that aint worth 20 bucks. shame on me.

I had the revtech version of that pack one pack has 40 cycles on it and swells when I run it and 1 pack dropped a cell. I ordered the black packs from fantom and there great , I believe there TP packs .

i agree, i have one of the black packs and they work great! the orange pack is what i have that is swelling. its the stupidest thing i have ever seen in RC. why make a pack that is so costly and a piece of junk at the same time!

That's not the battery's fault you stretched the runtime well beyond what you should have, or needed to have, stopped running it. Sounds like you did it to yourself.

obviously other people have had problem with this pack also... so why dont you buy one and run it how it should be and see if it swells on you too

Mine were ran in a t4 tc car running spec 17.5 blinky . charged at 10 amps and ran for 6-7 min at the longest

I run 2 of the 2s 6500 orange packs in my eBuggy. The batteries were bought last year and have been run down to the LVC many times. They haven't swelled at all. Did you follow the instructions that came with the batteries and put a soft cycle or two through them before heavy use? Mine always get two full charge and a 20amp discharge cycles before I run them.

It would be nice if people would first contact the manufacturer about problems with a product. Threads like this can effect a businesses sales and I like fantom. Personally I would've dealt with the company, not a forum.

How do you store your packs when you are not racing?
