Fyi- on my smy god s mod, which holds 3 batteries Sony vct-4. A small episode of the mod slipping from my hand about 1ft onto padded carpet resulted in the body of the mody getting very warm very quickly. I immediately moved mod to safe location to where within about 3 minutes #3 battery vented from top of battery. Yes i'm experienced and was not using mod in any other way than described. After mod cooled i removed backing and saw where #3 had vented. It looked like some leakage into mod. Unhappy I ended up discarding smy god mod S. I now have pioneer 4 you v4, and a v2
