Oh #%@!! What did I do to my SMC Lipos? - RC-Monster Forums

Maybe this was mentioned somewhere in this thread, but it looks like both packs puffed. Maybe it's just the angle of the pic (first one), but the one on the left looks puffed as well, just not as badly.

On a side note, I'm not really sure I like hard-case packs. Sure, they protect the lipos physically, but if they are tied down well enough, that shouldn't be a concern. My beef is that having packs enclosed doesn't exactly promote good airflow. And if they get too hot, they can puff. Maybe they were ok amp-wise, but since there was no cooling, they puffed anyway?

....id call em and see if they replace them... but remember to change gearing when taking the grass on. but in the end sounds to me the packs are bad.

I"m so upset I just wanna throw up. First my HDD fails on the 4th with all my data that I didn't back up, then my power supply croaks on my gaming rig last week, now this week my 50" Sony LCD screen has screen imperfection and NOW I can't drive my Flux anymore due to this Lipo shit storm.

I'm glad i'm leaving on vacation in a few days in the mountains, I hate everything tech wise right now.

I'm sorry man, you are having some bad luck lately... more like against all odds bad luck. I feel for ya.

Okay, if you do not need the 'most powerful' battery pack out there, then you should consider getting an A123 pack for your Flux, I am think a 6s2p pack would be a very good voltage for that motor. Hell man, I will even get the cells and build the packs for you!

You will be able to through EVERYTHING you could get the Flux to muster at the A123 pack and it would not give up on you, they are virtually indestructible, they last and last, and do not loose any performance over their entire life time.

Let us know what you are going to do.

Actually I tried A123 a few yrs back, bought 2 of the 2s2p 4600mah packs for an E-Savage, even the flashy Hypersonic Charger that A123systems brought out.

both packs failed in the first fortnight and got no reply from the company re warranty

Didn't work for me, but obviously working for you, just how it is I guess
