Battery size, weight and average fly time.

I found these batteries:

Rhino 4000mAh 3S2P 25C 11.1 V Lipo Battery

Would they be too heavy for an EXI 450??
I'm new to the hobby and not sure of these things, adn without being able to see it and compare to something else, I don't know.

Any suggestions??


Would this give a longer fly time, than say a 2200mAh 20C 11.1V???

Thanks,

Matt

Yes, they will give longer flying times, but they are WAY to big and heavy for 450 class heli. I think you should not buy more 2600mah battery for 450
