18650 Battery Holders

I needed some 18650 battery holders for my weather station I am putting together. So I made these ones. There are holders for 1, 2, 3, or 4 18650s. They use your standard battery terminals you can find them on ebay or amazon. These are the ones I used https://www.amazon.com/YXQ-Nickeling-Positive-Conversion-16mmx16mm/dp/B07T6DSKQP/ref=sr_1_15?dchild=1&keywords=18650+battery+terminals&qid=1610421606&sr=8-15
