|EXO Battery Unit|
Power source component used for construction of EXO items.
Batteries use electrochemical cells that store electricity in the form of chemical energy, and are able to convert it to electrical energy when needed. While most batteries have wet cells (or liquid electrolytes), the battery units in the new EXO rigs need a thermal reserve battery that must have the electrolyte (molten salt) melted through heating, meaning it can be stored for years and it won't discharge.
Developed for certain military applications, such as missiles or exosuits.
