Providing poor cells and marketing them as top-of-the-line is different than being off on cell measurements. Also, if you tell HobbyCity they're wrong they'll actually listen to you :wink:
I had a 2s 6000 "20c" (should be good to 120 amps continuous) die in a ~3 pound Traxxas Rustler geared 18/90 with a Mamba Max 5700 combo geared 18/90 running in the grass. I was getting motor temps around 160 before stopping to cool down, and the ESC was around 140-150. If I were pulling a considerable amount more amps than the pack could provide the motor and ESC should get much hotter than that, 120 amps is a lot. Mine puffed up like a balloon and I had to discharge it and toss it.
I had a 3s 6000 "20c" lipo that I ran in my FLM extended Stampede running a VXL system as well as the same Rustler as I mentioned above. I didn't run it nearly as hard as the 2s pack but after maybe 50 cycles the #3 cell died on me (wouldn't hold a charge at all), see pics below.
I had 2 2s 8000 mAH "20c" packs that I used at first in my converted Revo with an MGM 16018 and Neu 1515 1.5D geared 22/62 with stock Talons. I then switched to using them in my Muggy, same motor and ESC, with a 13T pinion and after 150-200 cycles they wouldn't take a full charge, got soft and a little puffy after a run, and would lose charge over time. Fortunately these ones I bought their warranty on, and I returned them before I had 1 year on the warranty so I got a free replacement (after 1 year you pay 33% of the replacement cost, 2 years you pay 66%, and after 3 years you're SOL). The warranty replacement is where Maxamps actually did very well by me. I shipped them back on Monday morning via USPS Priority Mail and received my replacements exactly 1 week later, via USPS Priority Mail. Figure 2 days each way and a 2 day weekend and they have a 1 day turn-around, RC-M is the business I've dealt with that has a better turn-around time than that (shipped Monday morning across the U.S. and had my replacement on Friday).
Their new lipos are said to be MUCH better than the old ones, but there's a snowball's chance in hell I'm spending ~$220 for a 2s pack they they claim is a 35C. They spend all that extra money on advertising and "gifts" for their supporters to keep them coming and to keep their "Reader's Choice" awards flowing. You don't really think you'll read something negative about ANY RC product in a magazine, do you? I stopped buying mags because of all the crap, they're so worried about losing advertisers that they won't give you the straight-up truth about a product.
And now for the death of my 3s pack:
