I have looked for a week now , everywhere and cannot find a replacement lipo for my Efusion Duo. Its sad I'm going to have to buy a new DNA mod for the 9v output I like. I messaged Lost Vapes several times and recieved no response. I messaged evolv and they replied with nothing. I thought I foound a fit , ordered the battery $50 , wow I know, and the place calls me and tells me they don't have the lipo pack I ordered.The one on Ebay does not fit before you mention that. I've gt nothing. Sad.
