Well, this has been a lesson learned the hard way. I did some reading of my Spektrum manual and the spektrum website. The website gives the below warning. The manual says NOTHING about the charge indicator lights. The only thing the manual says is that an alarm will sound and the LEDs flash if the battery voltage drops below 4.7. I never heard an alarm.
So anyway, the way I read the below warning is that a bad ESC, loose battery contacts, etc, could also have been the cause of my crash. Would rather believe that then the fault was mine for being stupid enough to fly with a not fully charged battery
.
So do I have any other battery options with the DX5 or do I need to upgrade to the DX6 to get the battery pack?

Do ensure your system has adequate voltage
The #1 problem encountered by DSM fliers: inadequate power supply. Unlike PCM, where servos get "crunchy" at voltages as low as 2.5 volts, the digital system used in DSM shuts down at 3.2 volts. 99% of fliers have no problem, but when you do, it's a toughie. New QuickConnect software allows restoration of your radio link the instant voltage is restored.
CAUSES
- Regulators heat up, losing voltage
- Use of new generation high performance servos without increasing power available
- Ni-Cd/Ni-MH batteries with poor capacity/high impedance that cannot deliver the wattage the system needs
- Add-on power supply systems are sometimes not robust enough to handle high current for extended periods of time
