Overview
This section specifies the extensions to the base motor/controller/battery combination circuit that is usually described in the manufacturer's instructions.
As described briefly above, the current Scottmobile version (V4) has 2 batteries, a (base) 48V Li-ion, and a (boost) 12V car battery. These batteries are wired in series to provide ~60V maximum for momentary use. The cruising is done using the 48V battery and/or pedals. Besides a momentary boost for hills, passing, starting from a stop, etc., the 12V battery also provides power to 12V accessories such as tail/stop lights, optional headlights.. that do not run on a 48V battery.
The other electrical systems that will be specified when they become available are:
The tail/stop lights, turn signals, headlights. The stop lights are the most important and will be implemented first.
The wiring of the solar panel and controller that can be used to charge both batteries independently of an electric grid as well as any other rechargeable device you may have such as power tools, cell phones, etc.. Of course, once implemented, this solar charging system provides free power.
The electrical circuits will be drawn in as simple a manner as possible using open source drawing software for circuit diagrams. Of course, these diagrams will be as "logical" as feasible with no physical implementation details such as manufacturer brands, etc. This allows you to choose the most competitive element (new or, especially, used) you can find to keep to your budget as much as feasible.
For example, all wire will have its gauge, and length specified to assist you in your search. All wire is copper unless otherwise noted.

o A purchased brake switch (crappy quality from Amazon - see picture). I suggest you use a 12V brake switch from a junked vehicle and adapt the mounting to suit for typical action (when brake pedal pressed, lights come on).

o 2 red LED stop lights wired in parallel (so if 1 burns out, other 1 will still work) via a 2 circuit connector strip and wired thru the vehicle fuse box next to battery under driver’s seat. This location was chosen for less chance of moisture problem than at front of cowl.
