how should i charge my 4xAA NiMh battery pack? Answered
a project that i am building is going to be powered by 4 NiMh batteries in series, i need to be able to just plug a cable(wall wart) into my project box to charge the battery pack.
there will be an arduino clone(with plenty of free pins to spare) available which i could use to control a charging circuit with it.
how many volts and amps should i charge the pack with? how do i detect the voltage drop when the batteries are done charging? is heat detection necessary?
the batteries are 2000mAh each btw.
