I run 2 of these in my stock genesis Im seeing temps around 60deg c after discharging the pack in around 5mins!!!! I have the strut quite high so the load is lessened somewhat also running a metal 440 prop sharpened and balanced.
I think this is too hot! though on paper these batteries should be fine......

I purchased 2 of these batteries. One seems to be fine, but can not use. That is because I need 2 batteries to run my R/C Truck. The second battery was defective on delivery. Shows only 3.8v instead of 7.4v. Took 3 weeks to get here. And now I am having problems with HobbyKing to warranty and replace it. "Send us pictures", "we need you to use special tester", that I do not have. "We sent to special department". I keep getting jerked around and very unhappy with this Company!!!!

Two of these packs arrived today one dead the other OK. It would appear they are not tested before sending, this could save a lot of problems.

I bought this pack for my Traxxas Slash 2wd with a Velineon system. The battery fits in the tray, but for some reason, the makers of these packs feel the need to run the power wires out the side, so I had to notch my tray so that the wires would fit. It was an issue with my Turnigy 3s, and even more so now because this pack has huge power leads. TURNIGY - PLEASE ROUTE THE WIRES OUT THE TOP OR FRONT OF YOUR PACKS!



With that being said, this pack has some SERIOUS PUNCH!!! My Slash wheelies easily, has a ton of run time (I'm guessing easily 20 minutes of hard driving), and the pack stays cool to the touch. I've charged it twice so far, and it took about 4400mah each time.



Before I bought this pack, I had a 3s lipo that was just too much to drive with and a 7c Sanyo NiCad that was a good pack, but not too fast and low on capacity. I didn't know how my truck would do going down to a 7.4v lipo pack, but I was pleasantly shocked at how much punch it had, and the top speed was fast enough to be fun, but still controllable. Overall, I'm very happy with how this pack performs.

I wish I could write a valid review. I ordered one of these batteries a month ago and haven't received it yet. This shipping time is non-sense. I could probably walk to Beijing before it's delivered here. Makes you wonder if the cost savings is worth the technology being outdated by the time you receive your goods.
