I'm building a new bicycle light and obviously killed the cheap driver I bought for it
. Now I wandered if I could direct drive the two Cree XM-L T6 wired in parallel from my AW 2900mAh protected cell without risking the cell to vent? The LED get very hot of course, but I think I could get rid of the heat while riding the bicycle.
As I used a small clicky switch (rated only 1,5 A, 220 V) and never learned to solder properly I think there is probably quite a voltage drop in my circuit. Am I right to assume, that from the fully charged cell the LEDs would only see about 3.7 V under load, so the parallel LED would share perhaps 4 A? Would that mean it is safe to use the AW 2900 in this light?
Thank you for your help!
