Battery Basics
When choosing a battery for your Slash 2WD, there are a few key specifications to keep in mind:
Battery Chemistry
NIMH and LiPo are the two main battery chemistry types used in RC. LiPo batteries are generally lighter weight and allow for higher performance. Most RC enthusiasts recommend LiPo batteries for the Slash 2WD.
Voltage
The voltage indicates the power output of the battery. Typical voltage ratings for the Slash 2WD are 2S and 3S LiPo batteries, with 2S being 7.4V and 3S being 11.1V. Higher voltage batteries provide more speed and acceleration, but may put more strain on the electronics.
Capacity
The capacity rating of a battery indicates how much charge it can hold, measured in milliamp hours (mAh). The higher the capacity, the longer the runtime you’ll get before needing to recharge. For the Slash 2WD, a capacity of 5000-7000mAh is a good range.
C Rating
The C rating indicates how much current a battery can discharge safely. Since the Slash 2WD is designed for high speeds and acceleration, look for batteries with discharge ratings of at least 20C or higher.
Size/Dimensions
Make sure to get a battery that fits the battery tray in the model. The Slash 2WD uses a shorty pack size.

Frequently Asked Questions
How long will a 5000mAh battery last in my Slash 2WD?
With moderate use, a 5000mAh battery will typically provide 15-20 minutes of drive time before needing to be recharged. Heavy use with continuous high speeds may shorten runtime closer to 10-15 minutes.
Is it okay to use a 3S LiPo in the Slash 2WD?
Traxxas recommends using 2S batteries with the stock electronics. While a 3S battery will provide more speed and power, it also puts more strain on the motor and ESC which could lead to premature failure.
Do I have to use Traxxas brand batteries?
No, you can use batteries from other quality brands. Just make sure to match the specifications for voltage, capacity, C rating, and size.
How long does it take to recharge a LiPo battery?
Most 5000-7000mAh batteries will take 1-2 hours for a full recharge using a proper balance charger. Always follow the battery and charger manufacturer recommendations.
How can I make my battery last longer?
Properly caring for your LiPo batteries by never fully discharging them, storing them at the right voltage, and avoiding damage will help maximize their lifespan. Following the “storage charge” guidelines will allow you to store them for long periods safely.
Conclusion
Choosing the best battery for your Traxxas Slash 2WD involves considering the right combination of battery chemistry, voltage, capacity, C rating, and size/dimensions. High quality LiPo batteries in the 5000-7000mAh range with discharge ratings over 25C are recommended for optimal runtime and performance.
Brands like Gens Ace, Venom, Zeee, Traxxas, and SMART LiPo all make great battery options to unleash the full speed and power potential of the Slash 2WD. With the right battery installed, you can enjoy thrilling runtime while bashing, racing, and jumping your short course truck.
