Hi
I am using this circuit attached which is fairly common method of getting a constant current of approx 1A to charge Li-ion batteries. however it just seems to be shorting out when i try attach the batteries. any idea why or how do i attach the batteries properly.
(the attachment shows a load where my batteries should be. Resistor is the same - which should provide 1A)
Or is there another way of getting a reliable constant current with Lm317?
Thanks
