Ezrun 5.5t 60a advice
 

I have a ezrun 5.5t 60a setup in my car and have just put a 11.1v 30c 80a lipo in the car, goes great but the esc is getting to hot and going into protection think I need a different speedy any suggestions?

Warrior! :thumbsup:

That speedo will probably struggle with 11v, it's more suited to a 7.4v pack.

What sort of car is it installed in?

How long does it last before it gets too hot?

Its in a tamiya rising storm built to this spec for a laugh last about 8mins I would say before it gets too hot I have now cut a hole in the body over the fan of the esc but thats untested as I have just lost a diveshaft.

a 5.5t is really pushing the 60a speedo, it's better suited to the 120a version. edit - i may be thinking of the Xerun! But i imagine the same applies to the EZrun

It may be ok for short stints and just about the 5 minute race lengths, but bashing it non stop until the battery drains is going to hammer the speedo.

60a ez run speedo isnt designed to run on 3s lipo!! 2s only! If you do want the 3s youll need the 120a ezrun speedo

yes 60a ezrun is 2 cell lipo only!!

I'll bet the motor is sweating its tits off too.:thumbsup:

Motor does not get that hot just the esc think I wil just have to get another esc is it worth getting the ezrun 120a or is there another cheap one that anyone would recommend

ExRun 120a (V2.1) is one of the best ESCs out there and can be had for about £100 ... absolute bargin!!!!

I thought the 120a was only available as an Xerun, not an ezrun?

If its this one you,ve got

the spec says you can use 3 cell lipo,s BUT your sreaming the nuts off it with a 5.5t motor. The 5.5 t motor should only b used with 2 cell lipo on road.

Yep thats the one I have have used it again with a hole cut in the body, temp seems to be down esc never cut out goes well though:thumbsup::thumbsup:

Sorry my bad, your right. I keep forgetting about the EzRun being sensorless ones.

I stand by my original (now corrected statement) that the ExRun V2.1 120A is one of the best speedos available and at £100 an absolute bargin!

Your still overloading the speedo by quite a lot. It only recommends 13t for 3cell lipo off road. It may be ok for a while but sooner or later your going to see the grey smoke. Get yourself a 2cell lipo battery before it costs you a new speedo.
