Trying to figure a way to use my KR808D-1 (Vapor King) batteries as "drippers". I found some vids on youtube showing that you can put a 901 atty on a KR808D-1 battery. The vids are kind of old and speak only of 901 attys. Well, my web searches for 901 always bring up DSE-901 attys. Are they the same or is the 901(without the DSE prefix) a different/discontinued model? Thanks in advance.
