Large Rechargeable Battery

Built for the night shift: solar charges it by day, turrets and a SAM Site drain it after dark. Same bench and research as the medium, double the materials.

Overview

In-game description
A Large Rechargeable 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.

Run your defences on solar and they go to sleep with the sun. This is the battery that keeps them awake. A large solar panel charges it through the day, and after dark it feeds an auto turret or the SAM Site on your roof until morning.

Look at the last two rows. Bench and research cost are identical, only the materials double: ten high quality metal and two tech trash instead of five and one. So once your group has a Level 2 bench, the medium only earns its place when tech trash is really tight.

It fills slowly, though, and a fifth of what goes in never comes back out. One panel on a big battery may not top it up before dark. Add panels, or a generator for the evening, before you add more turrets.

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.
