Nice.
Can you link to the convertor product not via Wish please? Just
looking at the URL makes me feel like my personal details are being harvested and posted on the darkweb ...
I know the feeling. Wish is the best deal on that part. DC-DC converters in small factors that are cheap are mutually exclusive terms. I have not found an alternative board through local sources. The board is such that I buy several at a time as I do get a dud here and there. I usually buy in such volumes and with all the parts research I do any information harvesting would create a self corrupting database anyways.
I did some burn in testing and the adjustable voltage is a great boon. The board gets hot if cranked to the full 26VDC output. I dial it back to a bearable light level and heat output is negligible. The heat is nothing I would really be concerned about. Housing the board in the battery is not a concern either as the airspace in there will be sufficient.
Regardless I am having to scale back my cosplay stuff so I can focus on home maintenance in the coming year to finish a couple of major yard landscaping projects and such.
