The zippy flightmax hardcase 4000mah fit perfectly into the stock setup E4RS.
The humps fit nice into the slots of the stock battery tray.
If you want bigger lipo's, then you nee Yodays battery tray.
I have been running the zippy's last year without any problems.
The car was only i bit to light(just under 1300 grams


).
cheers Roy
