Last Friday I used my QMX (12 V, 4 W out) on a summit. The radio was switched on about 35 minutes. During 30 minutes I had 15 QSO.
The LiFePo battery was full charged the day before. After the activation the charger showed 160 mAh for recharging.
This means:
- around 7 hours operation or
- 12 shorter activations
without recharging my 12 V 2 Ah battery.
IMHO a good value.
