Hi David, Powerstream ... http://www.powerstream.com/thin-lithium-ion.htm PGEB01180270 I've flown the smaller Sparkfun units (x2 for 7.4v) ... https://www.sparkfun.com/products/8483 and they work well, I was just really impressed with the density of the above ... I have a call in to Bob F., let's get his take on these since he has the most experience with them.... More on this later ... but I would be curious to know what other people are using ... :-) -James On Mon, Jun 30, 2014 at 10:27 PM, David Smith <davew6dps@xxxxxxxxx> wrote: > Where did you fund those?
