Due to its very small size, the Proto-X has a built-in LiPo battery that is not designed for replacement. Attempting to remove or replace the Lipo battery will likely damage the quadcopter. In addition, precise placement of the battery is critical for proper CG, balance and performance and isn't recommended for consumer replacement.
