OVONIC 11.1V 50C 3S 4000mAh Lipo Battery with XT60 & Trx Plug for RC Traxxas Cars

Can't beat the value here, great batteries for the price. And use for 3 months , so far not problem.

This was my first 3S battery, so I wasn't sure exactly what to expect when it came to power and performance. Battery size perfectly fits my Traxxas Stampede (its a little shorter than normal 3S batteries so it fits the Stampede's short battery tray) and boy, does this thing make my Pede rip! I can wheelie at any speed, and the battery lasts about 25 minutes going full throttle. The instructions say not to charge faster than 1C, but I charged it at 2.5C without an issue. The one downside is the discharge. After my esc shut off (low voltage detection enabled), the battery was only showing as having 3.6v per cell, which is a bit lower than it should be. To be safe, it should be 3.8v per cell, and my 2S does this without problem on my Pede. However, I can't say for certain this is a "fault" of the battery, so I'm not going to take away stars. Overall, very impressed with this battery for the price and super happy it fits in my vehicle (finding a higher capacity 3S battery that fit my tray was a real struggle). Ovonic is a good brand, and this is a solid battery. You won't be disappointed.
