Q. Why does my transmitter battery pack only last for under a half hour?
A. Make sure that you always charge your battery with the provided charger when charging through the transmitter. If you use a quick charger or "peak detector" charger remove the pack from the transmitter or you will not get a full charge. The minimum time it will take to charge your batteries with the included wall charger is 12 hours.
If the above has been followed and you still have short battery life, you may have a bad cell in the pack. Replace the pack in question.
