| 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 | |

| 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 |
