Battery advisory! I bot 3 batteries for my juicebox and 2 of them have failed(open circuited) in the last 2 days.Now I'm suddenly down to only 1 and naturally I'm quite worried about it.I got them from battery junction and believe they are closed due to a fire. Please correct me if they are still up and running. Anyway these are maybe some that you want to avoid.they are:UltraFire XSL 18650 2600mAh 3.7V.Red in color
