Because we believe that running a light with 2x(R)CR123 is dangerous\u003c\/span\u003e. Using two cells in series creates a significant chance of catastrophic failure if the batteries become imbalanced. Imbalance can be caused by batteries of different age, manufacturing defect, or difference in charge state. For example, you accidentally put in a charged battery with a discharged battery. This imbalance can lead to fire or explosion in one of the cells. \u003c\/p\u003e\n\u003cp\u003eThis is not uncommon. \u003cstrong\u003eEven if you think you are diligent, why take the risk when a much better option is available?\u003c\/strong\u003e This is also why we are no longer shipping \u003cstrong\u003eany\u003c\/strong\u003e Foursevens lights with 2xCR123 cells. \u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cspan style=\"color: #000000;\"\u003e\u003cstrong\u003ePROTECTION CIRCUIT:\u003c\/strong\u003e\u003c\/span\u003e\u003cspan\u003e These batteries contain a specialized electronic \"protection circuit\" for user safety.

Doing so will trip the protection circuit and render the battery inoperable. The Foursevens Flex Charger and Xtar VC2\/VC4 chargers are normally able to reactivate a tripped battery; however, this is not best practice and fully draining the battery causes long term damage to the cell. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #cc0000;\"\u003e\u003cstrong\u003ePLEASE NOTE:\u003c\/strong\u003e\u003c\/span\u003e Exceeding the maximum voltage of your flashlight can cause permanent damage to the flashlight.
