Traxxas 2849X Power Cell: 3S 11.1V 4000mAh LiPo Battery with iD Connector

Powerful, ready-to-use power for Traxxas models

The Traxxas Power Cell 2849X delivers dependable, high-current energy in a compact, semi-rigid package that minimizes the need for extra casing. Its design emphasizes direct integration with Traxxas vehicles, helping you keep a clean setup while staying focused on the drive. The battery chemistry and layout are optimized for performance-conscious users who value instant response and consistent output over long sessions.

With a 3S configuration, this 11.1V LiPo pack brings a steady flow of energy to demanding RC systems. The 4000mAh capacity translates to meaningful run times, while the 25C continuous discharge rating (100A) and 50C max burst (200A) support quick accelerations and sustained power without excessive sag. The semi-rigid form avoids bulky housings and reduces the likelihood of loose connections that can disrupt performance during high-speed runs.

Smart design, reliable connections

A new high-current connector with gold-plated copper terminals teams up with an integrated balance plug to streamline charging and reduce the number of potential failure points. The iD Auto Battery Identification feature works with compatible Traxxas chargers to automatically set charging parameters, so you can charge confidently and quickly between sessions. The MAXX cable uses a 12-gauge silicone jacket to maximize efficiency and help constrain resistance during heavy loads.

What you get and how it fits

Includes one 3S1P power cell with a high-current connector and integrated balance plug. The compact dimensions (5.3 x 1.02 x 1.7 inches) and weight of 11.1 ounces keep the footprint tidy, making it suitable for a range of Traxxas models without adding unnecessary weight.
