Giant’s latest EnergyPak battery systems feature streamlined designs that are integrated with the E-bike for a sleek and modern profile. There are two levels of EnergyPak—the EnergyPak Smart and EnergyPak. We also offer EnergyPak Plus, a range extender that helps prevent you from running out of power before reaching your destination.

This is our most premium battery technology and is cleanly integrated into the frame. It has an advanced Battery Management System for continuous communication between the battery and charger for optimized charging performance. EnergyPak Smart batteries can charge up to 80 percent in 2.2 hours (for EnergyPak Smart 500). It’s also compatible with our EnergyPak Plus range extender.
