Beeeeeeeeeeeeerry good! – 18650 Rechargeable Lithium LiFePO4 Battery 2-Pack (1350mAh) Reviews

Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

Pros:
regarding the con: on the anode it has 4 holes, where you can put a spring for putting the cells on series for diy.
fully compatible with many flashlights, etc...
mine came with 4.27v with 4.60amp.
Cons:
don't have the bigger tip on the anode, being hard to use 2 cells on series, on diy projects (not really a con)
lasts half the time of a common 18650, but it is not a con, it is a disadvantage of the LiFePO4.
NO CONS!
Other:
I had to built my own charger for these batteries, hard to find a cheap smart charger.
Bottomline:
buy it ! can even replace two AA cells (on some devices that could use 3.6~3.2 instead of 2.6~3v)
