![]() There are many great 3S ESC and motor options on the market, but the Velineon VXL-3S is what Traxxas recommends in the Slash. If you want to run a higher voltage pack in your Slash 4×4, you will need to upgrade to a brushless system, just like the 2WD model. You cannot run a 3S LiPo without risking damage to your ESC. If you own the brushed 4×4, you are in the same boat as the 2WD brushless model. The Slash 4×4 comes in 3 different configurations, and they are: So, you won’t break the mechanical components that drive the vehicle if you upgrade to a 3S motor and ESC. All Slash models come “3S Ready.” All that means is the drive train, spur gear, and pinion gear can handle the added power a 3S system produces. You CAN upgrade your 2WD Slash 2 to a 3S system by purchasing the Velineon VXL-3S ESC and motor combo. ![]() So, stick with the 7.4v 2S LiPo in the base model 2WD Slash. If you try to run a 3S LiPo in a Slash that does not have the VXL-3S speed control, you will break your truck by burning up the ESC. The XL-5 ESC has a maximum rated input voltage of 8.4v. You cannot run a 3S LiPo in a Traxxas Slash with an XL5 electronic speed controller (ESC). If you own a 2WD brushed Traxxas Slash, the biggest LiPo you can run is a 2S pack. In other words, running a 2S LiPo in your Slash will be like driving a four-cylinder Kia, and a 3S LiPo will be more like driving a V8 supercharged Camaro. More volts means more power! So a 3S LiPo will provide the most power to the motor. So, A 2S LiPo produces 7.4 volts while a 3S LiPo pushes 11.1 volts. The number of cells your LiPo has directly affects the voltage of the battery pack. LiPo batteries for RC cars are almost always wired in series to provide more voltage to the motor.Ī 2S battery has two cells wired in series, while a 3S battery has three cells in wired in series. The “S” marking on a LiPo battery stands for the number of cells the battery has. ![]() Let’s dive in! What Difference Will A 2S or 3S battery Make In A Traxxas Slash?īefore we get into the details of what battery I suggest for a Slash, let’s talk about what 2S and 3S means for the truck. But which one is the right battery for your Traxxas Slash model? In this post, we’ll compare 2S and 3S LiPo batteries for the Traxxas Slash and help you decide which LiPo is best for your new truck. If you are new to RC cars, you probably won’t have a battery and have to pick between a 2S or a 3S LiPo for your new Slash. When I bought my latest Traxxas Slash at Hobby Town, I was again confronted with the same dilemma: Should I get a 2S or 3S LiPo for a Traxxas Slash? Since most Traxxas vehicles don’t come with a battery or charger, you must buy both items separately.
