Quality and Performance – TrustFire Protected 18650 Lithium Battery (2400mAh 2-Pack Gray) Reviews

Involvement:General (knows how to use it) - Ownership:1 week to 1 month

Pros:
Cheap protected 18650 batteries - Great in applications that require 2xRCR123A's granted the application has ample room for the slight diameter increase and decrease in voltage is not an issue - Great runtime - Color scheme corelates to the protected status of the batteries - Short circuit protection - Protects your equipment from malfunction
- Long Run Time
- Quick Charging
Cons:
None
Other:
These charged up to 4.22v on my UltraFire WF-139 sku.1251.. Put them in my C2 Q5 5-Mode and the brightness and runtime is amazing, about 3 hours or more.. Runs getting dimmer afterwards but I havent tested how long.. It should be around another 3-4 hours before it dies in my estimation..
Bottomline:
If your looking for a well rounded protected 18650 batteries then this is the one to get.. In fact, get these over the UltraFire ones since they seem to be better and cheaper..
