Dual mount batteries

[J_MAN]

I've been looking on the forums and the Internet to see if anyone has come up with a dual mount for batteries for the P3. I know the older versions had brackets that held the batteries which in turn extended the flight time. Has anyone came across any websites or videos that tackle this idea?

Thanks

Not seen it.

The P3 doesn't lend itself well to such modifications.
Not sure this is the best platform if you're looking for more than an RTF aerial camera.
It accels at that and achieves a very good compromise of the physical and engineering trade-offs.
