Batpack is an IndustrialCraft 2 chestplate that stores EU and recharges low-tier electric tools in your hotbar.
Field Guide
Prepare rubber, RE-Batteries and insulated tin cable to craft the Batpack at a Crafting Table using the IC2 recipe.
Put the Batpack in the chestplate armor slot; this replaces any vanilla chestplate for the duration.
Keep a compatible low-tier device like the Mining Drill or Electric Treetap somewhere in your hotbar so the Batpack can charge it.
Mine, harvest or wrench as usual; the Batpack continuously transfers EU into the active tool until either tool or pack is empty.
Right-click the Batpack into a Batbox, MFE, MFSU or any Tier 1 charging slot — never feed it Medium or High Voltage.
The Batpack is a Tier 1 device. Hooking it directly to Medium Voltage (128 EU/t) or higher will destroy it. Use a Transformer to step down power if needed.
60,000 EU at Tier 1, which is roughly the same as six fully charged RE-Batteries.
No. It only charges compatible electric tools located in the hotbar, not in the main inventory.
Not in the same slot. The Batpack occupies the chestplate slot, so it replaces a vanilla chestplate; helmet, leggings and boots stay free.
Tier 1 devices explode or are destroyed when fed Medium Voltage (128 EU/t) or higher. Always use a Batbox or a step-down Transformer.
Yes for long mining trips, because the Batpack auto-recharges hotbar tools without manual swapping, saving an inventory slot and time.
