Oh, okay, seems I misunderstand how these things work. I see what you are saying now, I think. A quick peak now at discharging rate, shows it is around 115mA without solar panel. I do have a multimeter. I'm no expert at using it. With a 20 watt lamp over the panel, I get an output of around 5mA (again I maybe reading this wrong), or do I add a zero and it becomes 50mA? My apologies for being a dickhead where this is concerned, I did all this at school, many. many, years ago and have forgotten ALL OF IT! Thank you for your help so far
