Tamiya Battery: I followed the recommended course and found the

model car shop and bought one with a charger (actually not "Tamiya"
brand but the same thing for RC cars =96 7.2v, 3700 mAh, with the
Tamiya plug on it). The manual says that the machine automatically
detects these batteries and sets itself accordingly. However with the
Tamiya in, when I look in the menu the battery choice still
shows "alkali", if I manually set it to "RC7.2V" it then tells me
that the (fully charged) battery is nearly empty and only gives me
about 10 mins recording time before switching off, whereas if I leave
the menu set on "alkali" it performs as one would expect. Since it
takes only 4 alkali batteries (4x1.5=3D 6v) and the Tamiya is 7.2v I am
a bit worried about overloading something if it is not showing the
right setting. Does anyone else experience this ?

Thanks for any advice on these two.
