Voltage Difference Magnifier

(Summer Circuits 2010 article)

This circuit was designed for monitoring the charge- and discharge process of a 6-V lead-acid battery. This process takes place between 6.2 V and 6.8 V. The author used a measuring instrument that has several measuring ranges (0–1 V, 0–10 V, etc.). The 10 V range, however, is too coarse for this measurement.
