View source for Lithium-Ion Battery

=Basics=
*A Type of Electrically Rechargable Battery
*Has one of the highest power desities
*Can have a [[Battery Fire]] issue, also lithium availability may become an issue in the future (although recycling is possible)
*Most common form (pre-battery pack unit) OTS is the '''18650 Battery''' (similar in form factor to a "AA" type battery, different specs though)

=Depth of Discharge=
Discharging only a little bit and recharging prolongs life - 10 years if 10% discharge, 6 years if 25% discharge

=Cost= 
*$56 for 100 of 20Wh batteries - 3.7V, 5.8Ahr. 2000Whr for $56?

=Review=
This is a good review. Standard is 2200 Ah for 16850 cells, 3.7 v - 8 Wh of power. [https://www.youtube.com/watch?v=GlZtxSpIqT4]
*Ultrafire at 1 Ah and 4A is worth the $1.2. Cheaper than all others, for half capacity.
*Further - if it's 1 Ah and 72 cents - it appears to be 370W for $67, or under $200 per kW? Definitely would be worth it.

=Protection=
