As an off season project, our team decided we need a battery tester that can tell us if a battery is bad or going to be bad. So we did some research and came up with a simple load tester circuit. Since I haven't designed any serious circuit in over a decade, I would like to have somebody do a design review on the circuit before we build it. The detail of the design can be found here:
