Small Battery

The Small Battery (or Backpack Battery) is one of the types of Batteries in Astroneer which stores power up to a capacity of 2 columns (8 units). It can be placed in any slots.

Usage
Like the Medium Battery, it will be filled when connected to the network and all other Modules and Medium Batteries have been filled. 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 if a main battery (in a backpack, module or vehicle) require some.


 * Recharges & discharges rate = 1 unit/sec max.

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.
