So it’s not driven very hard…
Under load, figure those cells probably drop to about 3.8V… So…
3.56 A * 3.8 V * 3 Cells = 40.584 Watts being pulled from the cells
Assume 80% efficiency in the driver
40.584 * 0.8 = 32.467 Watts to the emitters
Divide by 9 Emitters
3.60 Watts per emitter. Far below the 10ish watt rating of an XM-L
