We envision a future network with hundreds of millions of active endpoints. These are not merely passive loads as are most endpoints today, but endpoints that may generate, sense, compute, communicate, and actuate.
It is not a guide on how to actually wire up equipment, terminate cables, use a soldering iron etc. It is not recommending which setups are good or bad.
The drawings are not wiring diagrams, they are schematics showing topology only. All wiring should be done according to equipment datasheets and manuals. All designs should be checked and installed by a qualified auto-electrician.
Every design is a compromise.
This guide gives you the info you need to pick your compromise. Dual Battery Systems A dual battery system is where one or more auxiliary batteries are installed in addition to the standard starter battery of a car, 4WD or motorhome.
Dual battery systems are common in touring vehicles set up for camping, fishing and travelling around the outback. One or More Batteries Whether there are one or more auxiliary batteries, and whether they are installed in the vehicle, under the bonnet, in the passenger cabin, in the tray or in a trailer, does not effect the design arrangements outlined in this article.
For the purpose of simplicity, this article will refer to only one auxiliary battery. A bank of batteries in parallel behaves the same as one large battery. All lead acid batteries behave fairly similarly.
When connected in parallel, batteries do not need to be exactly matched, as charge and discharge current will naturally distribute between them according to their capacity.
A larger battery or a battery with less internal resistance will sink more current when charging as it pulls down the charging voltage. Types of Batteries An auxiliary battery is most likely going to be cycled. That is, discharged at slow to moderate currents for long periods of time and then recharged.
This is different to a starting battery, which needs to deliver high currents for short periods, but does not get depleted or cycled significantly.
Cycling lead acid batteries wears them out, causing sulfation of the negative electrodes. Deeper discharges cause a disproportionate increase in wear. Double the discharge depth, and the damage to the battery is more than doubled.
Batteries used for cycling applications are specially designed to minimize wear caused by deep discharges, at the expense of reduced high current ability, increased weight and increased cost.Paul Kingsnorth is a writer and poet living in Cumbria, England.

One of the common features of an epic is the "fabulous loci" for the hero to visit. Fantasy novels can have some loci that are quite pretty or terrifying, but science .
