[NSRCA-discussion] Lipo For Futaba 12FGA

[Ron Van Putte]

Just to change the topic a while, I'd like to talk about lithium  
polymer batteries for transmitters.  Yes, I know that several  
companies sell polymer batteries for transmitters.  They come in  
square and flat configurations.  I've sold quite a few and every  
customer is happy; they only have to charge their transmitter battery  
every other month.

So, what do I want to talk about?  I can't find a "suitable" one for  
my Futaba 12FGA transmitter.  The 12FGA uses a 7.2 volt, 1600 mah  
battery.  A 2-cell lithium polymer battery would be perfect.   
Unfortunately I can't find one over 2100 mah that fits in the battery  
compartment (16x34x130 mm).  The problem is that most lithium polymer  
batteries sold now have more than a 10C discharge rate.  As a result,  
the batteries are bigger than necessary for a transmitter.   
Transmitters don't require more than 1C or 2C from the lithium  
polymer battery, especially the 2.4 GHz spread spectrum transmitters.

Any ideas/sources out there?
