The BatPack, or battery backpack, is a backpack filled with batteries that can provide energy to certain electric tools. It stores 60,000 EU, which is essentially 6 times the storage of a normal RE Battery.
The BatPack can be used as a battery or equipped in the Chest Slot. If equipped in the Chest Slot, it can provide power for any relevant tool:
Using a tool with BatPack energy available will charge the tool (up to twice per use) from the BatPack. In other words, if you take a halfway dead tool and begin using it with the BatPack, the tool's energy bar will eventually be full. When using a tool, the BatPack supplies the energy needed for that use, as well as charging the tool itself. It can also be used to charge a dead tool, by destroying a block when the tool has no charge, this, however, may be a glitch. ref The BatPack breaks from a moderate amount of damage, but only when empty. It provides one and a half armor points.
See: Crafting Guide
Alternatively it can be charged when worn by using the Static Boots or the Solar Helmet. They can be used in conjunction for greater charging, or replace each other when the charging requirements are not fulfilled.
Again just like a RE Battery, a batpack can be used to power machines.
|1.?|| The BatPack used tin in place of a wooden plank. It can be upgraded into a LapPack that can hold 300,000 EU. |
|2.? (Experimental)|| The BatPack uses a plank of wood in the recipe and the texture is changed to a wooden hull. The BatPack cannot be upgraded, but the Advanced BatPack is available. |
Using RE Batteries to recharge your tools is tedious. It can even be dangerous if you run out of power and have to stop and manually pick your Batteries while defending against hostile entities, so we even designed a special T7500-Rechargeable Energy Storation Unit Back Pack, which will automagically recharge tools as you use them. The little battery box is compact, safe, and can be carried on your back!
