Recently aquired a Sonic AD2K+ and wondering what kind of runtimes folks get
with external batteries.
Used this in the field a few times, and haven't had any issues yet, but noticed my
Tekkeon 3350 is dead after 2 hours 45 minutes. Tryed a few test runs at home
and thats all i can get from any of my 12 volt external battery packs. The same batteries
power my V3 for 5 hours and my R44 for 12 hours.
Is this the normal range for this unit?
