Performance & Handling

The MJX 7.4V 2S 3000mAh LiPo Battery transforms your MJX RC truck's performance by providing consistent voltage and ample current throughout extended driving sessions. The 3000mAh capacity delivers significantly longer runtime compared to smaller 1500mAh or 2000mAh packs, allowing you to enjoy 20-30 minutes of continuous driving depending on terrain, driving style, and vehicle configuration. The 25C discharge rating (75A continuous current capability) ensures your motor receives the power it needs for aggressive acceleration, sustained high-speed running on pavement and dirt, and confident hill climbing on grass and gravel without voltage drop that causes sluggish performance.

LiPo chemistry maintains more consistent voltage throughout the discharge cycle compared to NiMH batteries, meaning your MJX RC truck delivers strong performance from full charge down to the low-voltage cutoff. You'll experience responsive throttle control, predictable handling, and reliable power whether you're bashing through rough terrain, racing on smooth surfaces, or navigating technical obstacles. The hard-case construction protects the battery during inevitable crashes and rollovers, while the integrated protection circuitry helps prevent over-discharge that can permanently damage LiPo cells, extending the battery's useful lifespan through hundreds of charge cycles.

Technical Systems

Lithium Polymer (LiPo) batteries use advanced cell chemistry that stores more energy per gram than traditional NiMH technology, delivering higher voltage (7.4V nominal vs 7.2V for NiMH) and greater capacity in a lighter, more compact package. The 2S configuration connects two LiPo cells in series, providing 7.4V nominal voltage (8.4V fully charged) that's ideal for MJX brushed motor systems. The 25C discharge rating indicates the battery can safely deliver 25 times its capacity in amps continuously (3000mAh × 25C = 75A), providing ample headroom for motor current demands during acceleration and load. The hard-case construction uses rigid plastic to protect the soft polymer cells from puncture and impact damage, while the pre-installed connector ensures correct polarity and secure connection to your MJX vehicle's ESC.
