I have a bunch of Dewalt 18 V batteries and 2 LED shop lights that I converted to DC, specifically 60 V, 1.5 amps per strip. I have had mixed luck and I am looking for a better approach.
I have no problem building boards, but I was trying to take a short cut and I grabbed one of these: https://www.amazon.com/gp/product/B07L6F6S6S to boost 18 V to 60 V. This did work, but as the batteries drain the voltage went down and the boost went down proportionally, so the light did not last a long time. I added a 15 V regulator, but that got super hot.
Does anyone have an opinion on what is the right way to do this? I need to make a constant voltage power supply that takes 12-18 V and boosts to 60 V, which does not fluctuate as the battery drains.
