Medium Rechargeable Battery

The battery most duo and trio bases settle on: far more room than the small one, but it wants a Level 2 bench and a piece of tech trash per build.

Overview

In-game description
A Medium Rechargable Battery. Must have a minimum charge of 5 seconds to discharge. Can be wired in series. Charging rate is dependant on power in, with a maximum of 80% efficiency.

Tech trash is the price of admission here. Next to the high quality metal sits one piece of tech trash, and the blueprint needs a Level 2 workbench, so this tends to show up once a group has run a few monuments. In return you get a lot more room than the small battery offers, which is what a duo base with lights and a turret by the door actually needs.

  1. Place it inside, behind at least one wall and away from the door.
  2. With the wire tool, run a line from your source, a large solar panel or a generator, into the battery's input.
  3. Run a second line from its output to your lights or turret.
  4. Switch it on and give it a few seconds of charge before you expect anything to light up.

Keep the 80% from its description in mind: whatever you feed in, less comes back out. A panel that barely covers your daytime use will never fill it for the night. If the battery is empty every dawn, the source is the problem, not the battery.

Direct hit, hard side, no duds. Satchel Charge is a dud 20% of the time. Beancan Grenade is a dud 15% of the time. A range runs from point blank to the far end of the bullet's falloff, fired from an Assault Rifle.
