I need help setting up my chargers for my 3000 miah 7 cell nimh. I watched videos on YouTube before I bought them and seemed like it would be easy to set up but I'm not as smart as I thought I was. I tried to set it myself and when i hooked my batteries and turned it on, within 5 minutes the batteries were almost too hot to touch. the amps must have been wrong. If someone could help me out. Maybe a step by step instructions or video. Thanks for any help
