i use the zippy lipos there a bit wide but if you shave the tray a bit they fir just fine. i run a 5s setup
I saw your buggy build that u used mike's tray, are u still use it. Thanks for the info, but i will be using the RCPD one which is about the same dimension as mikes, but i don't know if it is as easy to shave down as mike's.
i put mikes tray in my truggy and now im using the rcpd one it sits way out and it needs a bit of shaving to fit the zippy 5000 its a nice tray though i wish the battery was moved over about 5mm
