I'm wondering if there's a value to a DIY Newb FAQ, for both cases. I was thinking of a format like below. This is only showing the proposed format and some examples that may fit into it. Anyway, I thought maybe a Newb specific sticky might be helpful, and easy to find if titled that way. Is there an appetite here for something like this? I know all of this can be found with a search, but my other observation is that new folks don't use the tool as much, since you kind of need to know what to search for, or how to.

The Parts of an Ebike System

General: You cannot build an ebike that can go 50 MPH with a 60 mile range for "$1000" If you have a donor bike, you expect to build one in some combination of 20mph to 27mph and 20 to 30 miles, for that investment, and speed vs. range is a trade off if your budget is fixed.
Batteries: If the deal is too good to be true, it is. A general rule, as of (Month/202#), for a pack made with name brand cell (Samsung/Sanyo/Panasonic/LG/Sony) $5 x the total number of cells in the pack is the minimum you should expect to pay. If the pack is made with generic Chinese "highest quality A grade cells", or similar description, you might expect to pay $3 x the total number.
- Terminology: Most lithium ion packs use series of cells that make up the pack voltage; typically 36V, 48V, 52V, and 72V. Respectively, the number of corresponding series cells for those voltages are 10, 13, 14, and 20. The total pack capacity (amount of energy stored) is based on how many series groups are placed in parallel, and the capacity of each cell. Packs may be described by voltage and capacity (52V 15Ah) or by their component make up (for example 14S5P), which describes the number of series cells (14S) and the number of parallel group (5P). The corresponding capacity for 5P depends on the capacity of the cells (for example 3000mAh) times the number of parallel groups (5 x 3000) or 15000mAh. 1Ah = 1000mAh, so 15000mAh = 15Ah.
- The Grin Motor Simulator is a great tool for determining how an ebike will perform based on the criteria entered; read of the instructions and start playing
- Trip Simulator - Change the Input at the top left of graph to Google Maps and right click your start point and end point then move the route line to your desired route by dragging the line holding the left mouse button down.

Kits Vs Turnkey
DIY Newb - Kit builder
Tools: Hand tools for installation; Digital Multimeter (DMM)
DIY Newb - Component builder
Tools: Hand tools for installation; Digital Multimeter (DMM); soldering iron and/or crimpers; motor tester
Displays: Displays from different brands are not compatible. The display must be the same brand as the controller for starters, but doesn't guaranty compatibility, so purchasing the controller with the display will assure compatibility.
Wiring: There are no wiring standards or wire color coding standards. If you are building from components, you cannot count on things working, just because you matched the wire colors on the connectors between devices. Use your DMM and realize that touching the wrong combination of wires can destroy electronics, instantaneously.
Spoke Calculator - https://ebikes.ca/tools/spoke-calc.html
5/3 - added general statement to General section and wiring to Component section. changed formatting, added torque arm links
5/27 - added 99t4 and markz contributions
Last observation: Most of the stickies appear to be threads that are made into stickies, so the information is scattered within the threads. It would be nice if when information is added by folks, that at the end the mods could consolidate into the main sections for easy access.
EDIT: Thinking about how a lot of members use translators when accessing the site, paragraphs probably don't work as well. I'm not sure, I don't use them much. Bullets are probably easier to understand.
