XRT 8S Battery Buying Guide

Battery Voltage

Just like other RC bikes, the 1/5 Traxxas XRT 8S can only handle certain voltages. It has a voltage limit of 29.6V, which is 2 4s lipo batteries, and if this limit is exceeded, a lot of heat will be generated which will damage the motor and ESC. Conversely, a low battery voltage will result in a lack of power.

Battery capacity

Simply put, the larger the “mAh”, the more power the battery can provide. This means you can get more runtime. However, a large-capacity battery often comes with extra weight. So you need to balance capacity and weight based on experience.

Soft Case and Hard Case Batteries
