Hello, I am building a red LPC-826 and have planned to run the diode off of this one driver. These diodes are meant to be powered no more than 500mA ±50, but I was told that drivers such as these could be used too? My plans are to run off of 2x 16340 (7.4v) to prevent early shut, instead of 1x 18650 (3.7). But the input voltage of the 17mm circular driver is stated to be 1.5v, is this power way to much that could be dissipated to heat loss? How about those special "circuit protected" boards for under volt supply? Thanks.
