Yeah, the pcb that goes over the positive or negative end of the battery.
I checked a couple of USA suppliers just to see if maybe they had anything good. I found these Vapcell 1100mah. Only 10 in stock, but shipping might be expensive.
You should also order a 18650 battery tube. They are pretty cheap. I don’t plan on ever using the short tube.
