Question - when flying two 4s 4000 batts in a series you are effectively using an 8s 8000 right?

No. It's still only 4k. In series you double voltage not mah. In parallel you double mah not voltage

8s yes but still only 4000mahs....Series doubles the voltage mah's stays the same.

Parallel is the opposite...Doubles mah's and voltage stays the same. Tom

If you want 8S and 8000mAh you need four 4S/4000mAh packs hooked up in parallel and series.

I think someone posted the math a while back because of the voltage or something...you get a little more out of the 8s setup with a few variables tossed in. The post is out there somewhere.

4000X8S=32000
5000x6S=30000
5300X6S=31800

With a Hacker A60-6XS (same as you) and with my ESC and BEC under the motor box, to get the packs relatively close to center of the battery tray (though they are a bit back from center), I had to put my rudder servo in the back.

Now as to the "C" rating of the packs, I am more of a sport flier, and do fly a bit faster sometimes than guys doing more 3D, so for me, the higher "C" rating works best.... YMMV.....

Batteries

Anybody using the Turnigy Nano-tech batteries. I recently picked up a 71" slick set up with a Hacker A60-6XS. I bought a couple of Turnigy nano-tech 5000mah 6S 45~90C Lipo Packs and my first flight seemed like after the first punch it didn't have any more punch left. I took it easy on the second battery so I really cant say how it did. Anyone have any expierence with these batteries? I hope they stand up to the job.

Personally, I don't like Turnigy packs, every one I have had, had no power, and puffed. My 71" Slick has the same motor and has plenty of power through the whole flight...but I am using Thunder power packs...

I've also experienced that with nanotechs. Not much punch to them.

Around here we call them nanowrecks, but maybe you will have better luck than us.
