This is the Traxxas 2S, 7.4V, 12,800mAh, 25C "Power Cell" Li-Poly Battery with Traxxas Connector. Traxxas Certified LiPo batteries are taking the guesswork out of going fast! These batteries have been engineered to give you the punch and on-demand power to reach the top speeds your Traxxas model is built to achieve. Available in a full range of capacities in 2-cell (2S) and 3-cell (3S) configurations, Traxxas Power Cell LiPO batteries are engineered specifically to fit Traxxas models and maximize their full performance potential. Only Traxxas gives you more of what you want most: simple installation, a great price, and the most speed and run time available.

NOTE: Traxxas LiPo Batteries should only be used in vehicles equipped with low voltage protection.

Features:
  • Semi-Rigid Construction: Traxxas Power Cell LiPO packs use a unique construction method that results in a firm, rugged, and compact pack that does not require a hard case. This allows Power Cell LiPo's to offer greater capacity in a given size, and also allows the user to easily monitor the condition of their battery. Unlike a hard-cased pack, if a Power Cell LiPo "puffs" or softens due to damage or abuse, the user can easily see and feel the change in the pack. Plus, there are no wire harness connectors that can loosen and fail over time.
  • Oversized Discharge Tabs: Power Cell LiPo's are constructed of premium cells with extra-wide discharge tabs. The discharge tabs are the actual contact points between the cells, so maximizing their surface area is critical to maximize pack performance. Power Cell LiPOs' extra-wide tabs ensure minimum resistance so more power and capacity is delivered on every run.
  • Hard-Wired for Maximum Durability and Performance: Power Cell LiPo packs feature High Current Connectors with 12-gauge Maxx Cable wire, soldered directly to the LiPo cells. Bullet connectors found on other packs introduce additional connections, increase resistance, and allow accidental reversed-polarity connections. Power Cell LiPo's rugged, hard-wired connection minimizes resistance to make sure all the power from your battery is used for greater speed and longer run times.
  • Standard JST/XH Balance Plug: Every Power Cell LiPo includes an industry-standard JST/XH plug to interface with the Traxxas EZ-Peak Plus charger and most other LiPo chargers. "Balance charging" allows each cell in the battery pack to be charged and discharged independently, assuring the cells are equally charged (balanced) for maximum performance and run time. For maximum performance, only use a LiPo balance charger with your Traxxas Power Cell LiPo batteries.
  • Factory Fit: Traxxas Power Cell LiPo's are designed to fit Traxxas models so you get the most capacity possible. Forget the foam blocks! Special "7-Cell" sized pack configurations maximize the capacity in your Slash, Slash 4x4 and other Traxxas models. The wires exit from the center of the pack to line up with the relief channels in Traxxas' chassis for a pinch-free fit. There are packs for every Traxxas vehicle, each guaranteed to fit properly and deliver the performance built into our models.
  • Lifetime Battery Exchange Program: Traxxas stands by Power Cell LiPo batteries with the best warranty and exchange program available. For the first year of ownership, Traxxas will replace any battery found to be defective at no cost. After one year, any Power Cell LiPo battery in any condition can be exchanged for a new equivalent battery for just 50% of the new pack's list price, no questions asked!

Traxxas 2S "Power Cell" 25C Li-Poly Battery w/Traxxas Connector (7.4V/12,800mAh)
I’m back for a follow up review. I love these batteries, and the LOOOONG run time they provide. I now have 2 of them, one for each slash 4x4. My average run time is 60 minutes with a stock velineon setup. I did have a couple problems though… Your front battery post is going to snap right off with an average front impact. It just wasn’t designed for such a big battery. That’s ok, take a dremmel w/cutting wheel and cut slits flush with the bottom of the battery tray, one on each side at the front of the battery, and one on each side at the back of the battery, so that a strip of Velcro will slip around the battery and through the side of the tray, across the bottom inside, and through the other side. Line the rest of the tray with the loop side of the Velcro to make a nice, soft tray. Stick a piece of the hook Velcro to the back of the back battery hold down support. Make another long piece of Velcro strap to go around the battery long ways, front to back. Fasten the long strap first, around the back battery support and fasten in the front, taking care not to torque battery wires (I actually run the wires between the Velcro – strap with a notch, wire, strap) this holds the battery back. Then fasten the straps that go around the sides, these hold the battery down and the long strap in place. NOTE - When installing the Velcro, I always made sure the soft loop side of Velcro was against battery. Your next problem will be over heating of your motor/esc, just because you’re bashing for so long. If you’re running a stock setup, get an esc fan and a motor heat sink with a fan and you’ll be fine. But if you’re a modified kind of guy – KEEP A CLOSE EYE ON TEMPS!!! You’ll be having fun, losing track of time, and before you know it, your motor is 260 degrees! The battery however, has never gotten hot. It is VERY UNLIKELY that you will EVER come close to the amp rating of this battery. In conclusion… BUY THIS BATTERY!!! Rig up your Velcro straps and motor/esc fans, and go have tons of fun!
