Inserted two brand new Tesiyi batteries in the Cuboid and they fit snug, but not overly so. After finishing a tank of juice I wanted to remove them again, but one battery did not slide out again. Long story short, the battery cover got hooked on the edge of the Cuboid battery housing and was stuck. The battery housing's top had a sharp edge on the one side allowing the battery to go in but not come out again. I had to take a small flat screwdriver and pull it out by sticking the screwdriver in the positive terminal's top. The cover tore off and a piece of the battery wrapper was stuck under the battery holder's plate. If it was only the cover I suppose I could re-wrap it, but the battery's positive terminal is now bent from the screw driver.
It seems the Tesiyi battery covers are thicker than the other batteries, because I tried some AWT batteries and they are very loose. Once I get home I'll try some Sony's and Samsung batteries.
