Voltage question fenix TK60

[Bushman5]

Ok , the tk60 can take 4 alkaline d cells, that's 4x1.5v = 6v

Or, one can use hi-capacity nimh d cells

The tenergy 10000mah nimh d cells are 1.2v each, 4x1.2v= 4.8v


So if I add another short extender tube (from the tk70), I can fit FIVE tenergy nimh 1.2v d cells in, for a total of 6v.

No issues with This? As I understand it the emitter can handle 7v ........

Thoughts?

There's no point in doing so. The emitter is XM-L correct? It uses a little over 3V @ 3A. The circuit will drop the voltage down to the needed level. In addition, the Nimh cells beat the alkalines in voltage supply on medium and higher modes already.

Awesome. Thanks for the reply. I was hoping to add more runtime with the fifth battery. That's interesting that the circuit drops voltage to needed level.

Thanks again. :twothumbs:twothumbs
