solar circuit not working properly? any ideas? Answered
I am building a solar powered charger for when I go on holiday, I know there are already some instructables on this but and can't seem to find anything to do with my problem.
I use the solar panels to charge Ni-MH batteries and when I test them in a simple circuit i.e. solar panels connected straight to the batteries, they charge but in my circuit below the battery connections on the casing heat up and the casing smokes. Obviously this is a problem but I don't know what is causing it.
My schematic is below.
