Hi guys, quick question about the safety of this setup.
Running an IMR-M3T bulb with 2x AW18650 2600mah cells.
Going by the data on Lumensfactory's site, the bulb will run 25 mins on 1600mah IMR 18650s, so using 20mins as a easier number to calculate I get a current draw of around 4.8A or 1.8C for the 2600mah cells.
Or just stuffing the bulb in a turbohead and driving it with 2x AW 2600mah 18650s and measuring the current at the tail cap I get a 3.2A at turn On and settling at 2.75A after about a second as the bulb warms up.
The bulb brightens slightly if I just short the rear cell to the body, so I assume my Multimeter is adding some resistance and affecting my results.
My question is, can I safely run the IMR bulb on 2x normal AW 18650 cells ?
And what is the maximum current I can safely pull from the cells before I start to either damage them, or risk having them vent with flame (something I don't want)
