'''Intent:''' This page is created as a guideline whether if assembling/designing your own battery pack is a viable option compared to buying a pre-made battery.
Prerequisite software/knowledge (before building a pack)


==Always wear a helmet==
Ability to draw 2D schematics/diagrams. - you need to do this if you are trying to make a pack with a certain dimension constraint. use of CAD is encouraged.
This can not be stressed enough, many people on bikes suffer head injury due to not wearing a helmet. Consider a full face helmet due to the higher speeds e-bikes often travel at.  


==Wear proper clothing==
You know how to use the [https://ebikewiki.com/index.php/Simulator|Grin simulator] - You need to know how much current your battery will be drawing.
Its best to wear long sleeves that cover the elbows, pants that cover the knees and securely laced up shoes to protect yourself during a crash. A thick jacket and glove are also highly recommended. Consider tucking your shoe lace ends into your shoe on the right leg to avoid them getting caught in the chain. elastics or Velcro strips can be used to keep baggy pants from being caught in the chain. It is especially important to keep your pants and shoe laces from being caught in the chain if you own a mid drive e-bike.


==Make sure your brakes are in working order==
Ohm's law. Since we are not going into AC power, complex number/angle is not needed.  
You need both back and front brakes in case one fails. This can happen and they tend to fail at the worst time when you need maximum braking. Test that both brakes work and get used to using both of them. The rear brake is good if you have to brake while turning or on slippery surfaces while the front brake is generally much more effective when you are braking in a straight line and have decent traction.  


==Look out for dangerous road conditions==
Ability to read battery cell datasheet. - As the wiki page becomes older, more cell info will be added to the page; but for cells that are not on this wiki/internet in a simplified format, reading datasheet will be necessary.

Ice, wet roads, wet leaves, pine needles, sand, gravel and other road debris can cause loss of traction on a bike, especially bikes with smoother tires. Consider testing the traction you have available with your rear brake when the roads are wet or frosty and ride cautiously enough to ensure you don't need more braking force then that.
 
==Be visible==
Wear bright clothing and/or install bright lighting on your bike. Even during the day time bright clothing and lights on your e-bike greatly help visibility. One popular option is installing daytime running lights powered off the e-bike's main battery with a battery voltage to 12v converter. Consider a wearing a high visibility vest if you want to ride at dusk or night time to greatly improve you visibility, especially if you intend to wear dark clothing.  
 
==Learn to ride at lower speeds==
You can expect to crash a few times while learning to ride a bike. if you don't have a lot of experience riding a bike its highly recommended you stick to lower speeds to avoid serious injuries when you crash. Consider each crash a learning experience on what not to do.

Intent: This page is created as a guideline whether if assembling/designing your own battery pack is a viable option compared to buying a pre-made battery. Prerequisite software/knowledge (before building a pack)

Ability to draw 2D schematics/diagrams. - you need to do this if you are trying to make a pack with a certain dimension constraint. use of CAD is encouraged.

You know how to use the simulator - You need to know how much current your battery will be drawing.

Ability to read battery cell datasheet. - As the wiki page becomes older, more cell info will be added to the page; but for cells that are not on this wiki/internet in a simplified format, reading datasheet will be necessary.
