The ARRMA® MOJAVE™ 4S BLX 4X4 Desert Truck is a marvel in the RC world. In this article, we’re diving deep into the world of batteries, specifically tailored for this RC monster. We’ll explore how the right battery not only ensures longevity and safety but also maximizes the performance, speed, and overall bashing experience that the MOJAVE 4S is famed for.
Tips: Battery tray size is 163mm*51mm*48mm (L*W*H).
Gens ace 4S 5000mAh 50C

Brand: Gens ace
Voltage: 14.8 Volts
Capacity: 5000mAh
Discharge Rate: 50C
Connector: EC5 Connector
Dimensions: 139mm x 46mm x 49mm
First off, the build quality of the Gens Ace battery is top-notch. The outer casing is robust, making it feel much more durable compared to some pricier options I’ve tried. That ruggedness is a perfect match for the MOJAVE, which is designed for challenging environments like dirt, grass, and even water or snow. While I’ve gone all-out, pushing my MOJAVE through puddles and snowy patches, the Gens Ace battery has stood up to the abuse beautifully.
Performance-wise, this battery has delivered consistent power to the MOJAVE. The 5000mAh capacity ensures a solid run time of around 20 minutes, which is impressive for such an aggressive driving style. Every time I’ve checked the voltage post a session, it hovered around the 14.8-14.4V mark, which means the battery maintains a good discharge rate throughout its use.
The 50C discharge rate ensures that the MOJAVE’s brushless motor gets all the power it needs to reach its 50+ mph potential. With this battery, the desert truck’s acceleration feels punchier, and the overall performance feels more responsive.
Zeee 4S 5200mAh 100C

Brand: Zeee
Voltage: 14.8 Volts
Capacity: 5200mAh
Discharge Rate: 100C
Connector: EC5 Connector
Dimensions: 154mm x 48.5mm x 32.5mm
Weight: 518g
To begin with, the cost-to-performance ratio of this battery is striking. It’s not every day that you find a battery that delivers top-tier performance without burning a hole in your pocket. The fact that it’s a softcase lipo makes it notably lighter. While some might be skeptical about softcase batteries, I found that the weight advantage it brought to the MOJAVE was game-changing. The reduced weight ensured better handling, especially when making sharp turns or navigating tricky terrains.
Power is the essence of the Zeee battery. With a whopping 100C discharge rate, it infuses the MOJAVE with the energy it needs to roar to life and maintain a steady, aggressive pace throughout its runtime. I’ve mostly run it on flat surfaces and racetracks, and this battery consistently allows the truck to hit around 50 mph without even needing a pinion change.
The 5200mAh capacity is another boon. It guarantees a long and exhilarating drive, ensuring that I can spend more time bashing and less time charging. Its compatibility with the MOJAVE is further accentuated with the EC5 connector, ensuring a stable connection and optimal power flow.
However, the dimensions of this battery are slightly bigger, so ensure it fits snugly in the MOJAVE’s battery tray. Given its weight of 518g, which is relatively light for its capacity, the center of gravity remains balanced, ensuring the truck doesn’t tip easily.
