I had a bit of puffing with the 2S 9000mah packs. I run them in my brushless revo and savage flux. They puff ever so slightly after a few months, but don't seem to get worse. I've been running 4 of them for 16 months, at least 75 cycles. Probably closer to 100. I balance charge at 10A, always put into storage mode at the end of the day, LVC's set at 3.5V in both trucks. I started to notice they are taking longer to charge from empty or storage the past few months and run times aren't quite as long. I was averaging 45 minutes at the skate park and 35 at the park (more WOT running). Now it's more around 37 minutes at the skate park, 27-30 minutes at the park. I'm not buying the 9000's again as they don't fit in all 4 of my trucks, but the 7400's do, so I'm going to just run those. They have a higher C rating than the 9K's, and the run time isn't that much less. They do perform better when I run them in my erbe/savage flux overall than the 9K's as well. I just ordered 4 more of the 7400's, so I'll have 8 of them. I'll continue to use the 9k's until they die.
So maybe you can give me some ideas on this I bought a used X maxx it came with two of the 4S Traxxas 6700 batteries one of them is fine but one of them is just slightly and I do mean slightly puffed maybe only a mill or two I could send it back for a possible warranty but not sure if they’ll cover it or not do you think it’s safe to keep a running list as long as it doesn’t get worse
For my limited fleet of rc vehicles, I have 3 LiPo packs. One of them is a Gens ACG 7000mAh, 60C 4S pack purchased a year ago for my Armma Kraton. The thing runs great and I have had absolutely no problems with that pack. On the other hand I also have 2 SMC LiPo packs also purchased a year ago from SMC online. One is a 2S, 5200 mAh #52112-2s2p,. It is bulged out on the sides and must be disposed of. The other is a 4S, 5200mAh, # 52112-4s2p. That one will not take a balance charge. Only one of the 4 cells will charge to about 4.15volts. The other 3 cells will not charge above 3.8volts. Have tried several ways of charging that one without any success. That one will also have to be disposed of. None of these packs have been abused in any way other than running them in the vehicles for short periods. No more SMC batteries for me.
Just for the record, Ive been very impressed with the SMC battery I've had, and plan to get more. However there's always a question regarding c rating with batteries. Correct me if I'm wrong here, but the Kraton is running a 150amp ESC. But The SMC lipo you have is only rated as stated, for 90c @ 131 amp. Since your esc is rated higher, youd be better off comparing their next model up. When amp rating on a lipo is below the esc rating , I've been told that the esc tries to pull that from the lipo, but can't, which means the power will often not be as high as it should, and perhaps not even as high as a lipo rated for higher amps with a lower c rating. Could possibly explain why the turnigy has more power. If this doesn't make sense then just disregard, I'm still new to this hobby, I could be mistaken. Also, SMC make a special series of extreme output batteries which are meant for high performance but don't last as long. Might be a good comparison to the turnigy to test one of those as well. Not sure how long the turnigy last, but I always hear they're great overall with loads of constant power. Boils down to price for me.
You will also build heat. Higher discharge batteries have lower internal resistance, usually coupled with higher capacity. By pushing an underpowered battery, you WILL eventually build heat and puff the battery. Always go overkill on batteries, prevents failure and possible fire
Garrett Bralley this smc is the worst Lipo I have ever had. Cell 2 has always been lower then the other cells after running it. It will balance on the charger but it puffed up after less then a month. When I contacted smc shortly after I received it with pictures showing that cell 2 was not balanced they blamed it on my charger even though all my other lipos are fine. I know occasionally you might get a dud Lipo but when they didn't stand behind their products they lost me as a customer.
I got 4 full runs with my 6s SMC and its slightly puffing to where when its on the narrow sides on a table, its rocks. I do all the tricks and tips on taking care of lipos. I balance charge it at 9amps (9200mah), i store it at 30% if not being used longer then 1 day, each cell is at 3.8ish volts, max volts on charge is set to 4.150 per cell (SMC box said 4.2 and below is good) i dont run the RC hard and im not sure what i left out and w/e it is, im doing it. Not sure if its normal for that pack to rock, maybe they dont make them perfectly flat, i never tested it on day one but i dont recall it being that bad. My next pack is going to be turnigy, the big black one.

Depends on max mah capacity and rated charge rate. Check your specs. For example, my recommended charge rate on my 5000mah batts are 5amps, 1c an hour for every 1000mah. 5k, 5amp charge rate
L3G3NDB0RN I am still running this Lipo but it is puffed and cell 2 is always out of balance when I go to charge it after running it. It will balance out on the charger but it takes longer then my other lipos.
That was a good endorsement for Turnigy!! I've been in this Hobby since 1985..... and I am BRAND NEW to Lipo Batteries!! I've finally convinced myself that they're not going to instantly EXPLODE. 💥💥🌋🔥🔥🔥 I have no idea what I'm doing! That's tough to admit for someone with so much experience. Starting small, I've got a 2S, 40C, 4000mah, and a 3S, 45C, 3500mah.... I can't even Charge them - because I have NO IDEA how to use my new IMAX B6AC Balance Charger! 😞😠😠 All it does is display "0.00V", 6 times across the screen, and none of the buttons do anything. When I plug in the Balance Plug, I'll get a "3.88, 3.91, 0.00, 0.00, 0.00, 0.00" (with the 2S). ANY idea what I'm doing Wrong???
I just invested in a 3s 11.1 volt set. 9200mah at 90c discharge. I only require a 30c discharge on my xmaxx at 11.1 volts, so these new batts should be well into overkill for the truck. 77 bucks a piece. I'll make sure to get my 2 cents out there after I cycle them. Imo, I think people are buying batteries and using them for applications that require higher discharge rates, causing the puffing. Nobody really does the math they just want the cheap ones! Lol
Check your IR. Might be a bad battery. I’ve gotten 75C battery from someone I shall not name and had ridiculously high IR. Had it replaced and it’s been good ever since. IR is what determines the C rating
Next time you get batteries check the IR and voltage first thing to make sure they’re not faulty. All my RC lipos have less than 6ohms combined IR. Some have less
Nobody really seems to pay attention to resistance and discharge rating... out here giving batteries a bad rep quite possibly because their internal resistance didn't fit the application and they built too much heat. If a battery gets hot in the first couple minutes of a run, stop using it and find the right battery.
