The 100 watt LED chips are attractive for tinkering. Suppose I get a chip and want to power it with a 250w DC-DC CC Boost Step-up power supply using 18650 LiPo battery pack. I read I need ~32vdc at 3a to run these chips. The DC-DC Boost accepts 8-48vdc input and outputs 12-50vdc at 0.2-8A. Theoretically, I could use a simple 3S 18650 pack or a 3S2P to increase mah. Alternately, I could run a 6S2P 18650 pack. Seems the less batteries in series the better but the boost converter will run hotter. What are most people doing to properly power these 100 watt LED chips?
