What should the exact cutoff be to prevent over-discharge? How much current compliance is required just prior to that cutoff voltage? What's the current compliance (if different) when the battery is fully charged?

| Jul 5 at 1:06 | comment | added | jonathanjo | I think your arithmetic is a little off: (5600 / (5600 + 1600)) * 7.2 is 5.6V, not 4.7, | |
| Jul 5 at 0:21 | comment | added | John D | Your zener has 10 uA of leakage with 1 V across it. What's the beta of your transistor? With a few volts across the zener and a high beta transistor you could get some mA of collector current. You might try a base-emitter resistor so that the leakage isn't directly becoming base current. | |
