I just bought this blue laser from a dude in China, but it's without batteries and I am not sure which ones to buy. It needs two 16340 batteries, he says.
The laser should be able to power out 200mW (real output power the seller said, although it says lower in the add). I tried a 18650 3.7V 6800mAh battery that I had from another laser, but the beam was very weak and certainly NOT burning power.
So my question is, will it have higher output power with two 16340 batteries 3.7V? Shouldn't it be the same power output, regardless if you use one 18650or two 16340? Some people say yes, some say two of the 16340 will give 7.4 V and therefore more output power.
Which is true?
Another issue is apparently lasting time. The 16340 I have seen with a max of 2000mAh.
Which batteries to buy and where?
