Lithium ion batteries can combust when improperly charged or discharged and can't be extinguished by water. as such there are only a few retailers we are willing to endorse. Its highly recommended to go with these resellers or at least do serious research on who you plan to buy packs from. Do not buy battery packs off random ebay/amazon/aliexpress pages, their quality often leaves much to be desired.  
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.


==Where to buy:==
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.
We currently recommend the following dealers.


[https://em3ev.com/ EM3ev] - High quality hand-made batteries shipped from China. Comes equipped with a bluetooth compatible BMS so you can monitor your batteries health and performance with a cellphone app. Highly recommended.
Ohm's law. Since we are not going into AC power, complex number/angle is not needed.  


[https://lunacycle.com/18650-ebike-battery-pack/ Luna Cycle] - high quality batteries shipped from USA
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.

Unit Pack Power used to be on our list, but due to several recently raised safety concerns and a couple of known fires, we no longer recommend this seller
 
==Reputable Cell Providers==
 
Here, we are listing battery cell suppliers known by members to sell legit cells. Cells are purchased only when someone wishes to make a DIY battery pack.

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.

Ohm's law. Since we are not going into AC power, complex number/angle is not needed.

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.
