I don't know if you have any experience in battery operated devices but I looked up some NiMH discharge curves and some NiCd curves. they look quite the same do you think it is safe to calculate the time the controller will operate with: Capacity/current*0.95 the 0.95 since my power drain is 20 mA at a battery capacity of 600maH (0.03C) Regards |

| depends on battery type | 01/01/70 00:00 | |
| what's a buck boost? | 01/01/70 00:00 | |
| a Buck/Boost is a switcher that will make the outp | 01/01/70 00:00 | |

| Very simple! | 01/01/70 00:00 | |
| Remember, though: | 01/01/70 00:00 | |
| So what? | 01/01/70 00:00 | |
| 1.2V | 01/01/70 00:00 | |
| Ah sorry. | 01/01/70 00:00 | |
| Confusing the numbers... | 01/01/70 00:00 | |
| Lithium Ion | 01/01/70 00:00 | |
| and 3.7V | 01/01/70 00:00 | |
| Not for beginner | 01/01/70 00:00 | |
| combine AA & AAA | 01/01/70 00:00 | |
| So, you intend to use NiCd? | 01/01/70 00:00 | |
| Not a good Idea | 01/01/70 00:00 | |
Minimum capacitiy per cell must be 1300mAh! | 01/01/70 00:00 |
