=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=
*Protected vs unprotected - [https://www.ebay.com/itm/Lots-100x-3-7V-Li-ion-Rechargeable-Mod-Battery-ICR-18650-2200mAh-Flat-Top-PKCELL/282226490818?hash=item41b6027dc2:g:7GQAAOSwVvpZk7Td]
