Energypack

The Energypack is an upgrade to the Advanced Batpack added by IndustrialCraft 2. It stores about three times the amount of power as the Advanced Batpack.

Usage
In order to charge it, place it inside something like a MFE. If you use a tool that is in any stage of discharge, using it with an Energypack equipped will charge it as much as the Energypack can (full if possible).
