Supply:  dual Li-Po 7.2V-8.2V

Feb/14/2012

When you try test  your receiver, you might take to another place for better signal. you can chose 9V battery . and a special connector.

But , the most inconvenience is, it's low capacity, not suppory large current, no long life, then it became expensive.  So, pick up 2 old cell phone Li-Po battery, series them together, you got 7.2V lowest to highest 8.4V  portable power box, a small( match box size) metal box seal them together, everything is amazing now, carry your supply anywhere you want. not stabilised.  

for more usage,  a little bigger box with 3 series more power Li-Po built-in charger might a very attractive idea. but not now.
