Has anybody ran a Convoy 12 mode driver off 2xCR123? I have a C8+ which I would like to use as a travel light but need to make sure I can run primaries as an emergency back up. Will it just dump the extra voltage as heat?
I don’t know but if you need emergency backup you are better off with a AA flashlight. CR123A aren’t very good, an 18650 has more energy than 2xCR123A and they can’t handle more than 2A, if you run them at 5A by accident they could even explode.
The 12 mode driver is 3 volt or 6 volt or even 12 volt depending on the light.l since it comes as mainly firmware not a specific driver size/configuration. In a C8+ its going to be a 17mm 3 volt version so 2 CR123A lithium cells is over 4 volts (3 volts each) and will kill the driver a cause it to release magic smoke. You need a buck driver to be able to do that.
