The EF03446 is a 3.6V lithium battery module for the Smart Cutebot Car. This module allows the Cutebor car to have a stable and rechargeable power supply. Having an onboard power management system is so much easier than traditional batteries! Plus! We've made two custom holes that make it possible to integrate them into your Lego projects.
Note: Lithium battery included
