This is the "starter edition" of the Battery Shrine from earlier this year.  The only thing it does is move cargo.

As configured, works for empty accumulators, as this IS a blueprint for managing the accumulator supply.  HOWEVER, this print will also work for other bulky items you may need to manage in huge numbers...like sails or rockets.  Just replace accumulators in the ILS settings with the other item.

Default Values:

GREEN switches = 36,000 items
YELLOW switches = 72,000 items
RED switches = 108,000 items

You may alter these values by stacking more boxes atop each color storage.  As configured, each can max out at 288,000 by stacking every provided storage up to 8 high.  

You may EXPAND all included storage as well--each one is pretty easy to chop apart in the middle so you can do some quick cut-n-paste expanding.  You can also clone the rising belt structure that goes from each switch to its larger storage portion, and add another layer that way.

INSTALLATION:

Plunk this down in an equatorial area.  Check the MK1 storage for each of the switches.  Each storage has preconfigured slots: foundation, red/yellow/green cubes.  Supply 'em, put 'em in the boxen.  Supply power to either end, but do not have any power covering the switches.

(If you want to cut-n-paste the switch arrays out and run them at the ends so this will fit in the first tropics, they're a pretty easy set to expand--just clone the belt span between switch and array and use that to connect them from afar.  You'll need more foundation and cubes, though.)

The little rings of MK1 belts show where to put Tesla Towers to turn on each switch.  Destroy the tower to turn it off.
