Arne, Consider that the transmitter has very little pulse load
requirements, that is, the current drain is relatively constant so cell
resistance is a minor consideration. Therefore, the NiMH battery with its
superior capacity at moderate current is a better choice. The only downside
to NiMH is a higher self discharge rate. So figuring 2% per day, you loose
a little over half capacity in a month. That is still three hours of run
time left for a typical TX with a good safety margin. I was convinced a few
years ago and it has been working out very well. Either way, you have run
time for anything except a Level 5 slope attempt!
