Small Battery

Description
The Small Battery (or Backpack Battery) stores power up to a capacity of 2 columns (8 units). It can be placed in any slots.

Crafting
The small battery is crafted in the backpack, using 1 Lithium.

Usage
Like the (big) battery, it will be filled when the network it is connected to produces energy and no other batteries have priority over it. That is when all other main batteries are full and there is no other empty batteries closer to the energy source.

The battery will give away its stored energy whenever the network doesn't produce (enough) energy and exclusively a main battery (in a backpack, module or vehicle) require some.

TODO : find out the max rate at which energy is given.

When placed in the backpack, it increase the total energy storage by 80%, from 10 to 18 units. So a single small battery in the backpack, yet visually a lot smaller than the main battery, almost doubles the storage and the time you can spend mining while not tethered (or no other source of energy is available). Energy will be drawn first from the small battery over the main one but as said above will only be filled when the main one is itself full.

TODO : check if battery can work when in one of the backpack's side slots
