Battery Bank

Description
The  is a new tool added in A16 as a part of the new Electricity game mechanics.

The Battery Bank allows you to power your electrical components. It requires at least one battery, expandable up to six. The maximum energy output is determined by the number of batteries installed and their quality. An externally powered and turned on Battery Bank will recharge its batteries. If there are no batteries installed it acts as a relay pushing power down line.

A battery bank is best when paired with a Solar Bank, which can recharge the batteries during the day.

Discharging
While turned on the battery bank will consume durability from batteries in its slots starting with the top left. These batteries will lose durability at a rate of 4 points per minute per watt. So if your battery bank was producing 45W of power it would use 4*45 = 180 durability per minute.

minutes_of_charge = durability_of_battery / (4*power_usage)

Charging
To charge a Battery Bank attach it to an alternate power source (e.g. a Solar Bank) by right clicking the source with a wiring tool then right clicking the battery bank. Note the battery bank must be turned on for it to charge as while it is off it is considered bypassed so only acts as a relay.

While charging it will consume 5w from the alternate power source (so to charge a battery bank you need system_power_cost+5w). While powered, it will regenerate durability in the battery inside, independent of quality, at a rate of 6 points per second. Batteries are charged in the sequence right to left, bottom to top. A 600 quality battery has 6000 durability so it would take about 16 minutes and 40 seconds to charge making the maximum time taken to fully recharge a battery bank 100 minutes.
