#134609 - Lithium Ion Responding to: ???'s previous message |
Li - Ion has a really even discharge voltage and his one of the hightest power to densisty ratios. They run at 3.0v but, you could double them up and use and effeint switching power chip. National Semiconductor has some good one if I remeber right. there probly buck down buck up circuits.They where in the 90%+ effiency rating.
this route can get expensive thu. |

| 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 | |
