Energy

Seabases

Seabases require Energy to produce breathable air and to power appliances such as the Fabricator, Power Cell Charger, and Battery Charger.

Seabases will draw power from internal generators (Bioreactors or Nuclear Reactors) installed inside the base and from any external generators (Solar Panels or Thermal Plants) within power transmission range. Power transmission is represented by a thin glowing blue line connecting an external generator to the base. The Power Transmitter can be used to connect generators to bases across greater distances. Power is drawn from the oldest generator first, regardless of type of generator. Each generator will work to fill its own internal storage capacity and will not fill the capacity of other generators.

Lifepod 5 consumes and produces power much like a seabase. It draws its power from three special unremovable power cells, and it generates power from a built-in solar array during daylight hours.

  1. Actual output depends on how much sunlight the panel is receiving, see the Solar Panel page for details.
  2. Actual output depends on the temperature at the Thermal Plant's location.

Items and vehicles

Some items and vehicles require a Battery or Power Cell to operate. Their upgraded variants, the Ion Battery and Ion Power Cell, can also be used in place of their normal versions.

When Energy runs out, the player can replace the empty power source with a Battery or Power Cell from inventory. For handheld devices, equip the device and press the Replace key (default R). For vehicles, interact directly with the empty power cell.

  • The Seamoth's power cell is on the underside, towards the rear.
  • The Prawn Suit has two power cells near the storage.
  • The Cyclops has two banks of three power cells, on either side of the engine.

The Seamoth and the Prawn suit can also be recharged by docking at a Moonpool or Cyclops. While docked, they recharge at the same rate as if their power cells were in a Power Cell Charger.

Replacing a partially or fully depleted battery or power cell will give the player that used battery or power cell. They can be recharged using a Battery Charger or Power Cell Charger both of which draw power from a Seabase or the Cyclops, or by installing the appropriate upgrade module.
