Edit: nevermind the pic on HW's site, which shows the blue ESC with no cables! It comes as shown on the pic of the black one!
(They are the same, anyway, apart from color!).

I have read your link and its good to see this information but i dont agree with the c rating part and you know why ?
Its because there is a standard to test the c rating of battery's and why doesnt the manufacturer set aside the true rating batterys and mark them as they are like they did with the matching of nimh......

Never. 40C is 200A. (in a 5mAh RC car batt)
Using welding cables in our cars??
Read below, taken from Hyperions warning regarding C ratings
"Note that NO CONNECTOR SYSTEM in use for RC Cars matches these rates, nor do RC cars draw such high continuous currents. Therefore if you intend to do CELL testing at max C rates continuously, hard case must be disassembled and appropriate cell connections made, by expert users only. RC CAR Standard connectors have ratings of 20A to about 80A continuous max depending on type, so never exceed connector ratings on continuous basis."

The 60A blue Xerun comes with 5 wires attached to the ESC. Three wires for the motor and two for battery, all color coded, but they are naked on the other end . no plugs.

Its because there is a standard to test the c rating of battery's and why doesnt the manufacturer set aside the true rating batterys and mark them as they are like they did with the matching of nimh ?if they made 1000 battery's and 30 percent were 28c and the rest were 35c is it correct to mark them all35c and sell them at the 35 c pricing ?when 30 % of them are 28c ?I can understand a tolerence of plus or minus of 2-3% but not 20%
I think its totally wrong dont you ?

hi i am fairly new here (just getting back into rc cars) and was looking for information on the xerun 80a esc
i brought one and it has a black case and thought it maybe a older version
i havent got it yet but it didnt say version 2 just updated ezrun.
was there a version 1 that had a enclosed fan like the blue ones shown on the hobby wing site ?
i will throw my 2 cents in about batteries
first there is only a few places that actually make lipos, so the cheap are made at the same factory as the expensive ones in a lot of cases.
i run brushless boats,for those not familiar with FE they push motors,esc,batteries harder than any other rc vehicle.
in testing lipos using data loggers i have seen cheap lipos that have a 20c rating and 5000 mah capacity that could not sustain 20 amps constant
i have run setups were the data logger which will accurately read up to 180 amps wont go any higher,so its pulling in excess of 180 amps under load
and constant amp draw of around 160 amps
so for those that say they cant they can pull around 200 amps from a 5000 mah pack.
in some testing a friend of mine did he ran a rigger with a $300 battery his top speed was 76 mph he then tried a turnigy battery worth around $50
it ran a top speed of 73 mph,so the more expensive battry was faster but to me 3 mph for $250 is not a good deal.
imo there is a lot of difference between a cheap nasty pack and a cheap good pack
just because some thing costs 5 times the price doesn't make it 5 times as good.
its very easy with rc gear to get sucked into the " new model is better" crap that goes on

Guys,
It has absolutely nothing what-so-ever to do with my battery C rating.
HW have stated this is normal behaviour for the LVC and i have asked if this can be changed to another less "stops everything" kind of LVC.
The C rating of LiPo's is a major other discussion with no real answer and has nothing to do with this thread.
Can we please not bung up this thread that has fantastic advice with something nothing to do with the topic.
Cheers
Mark

It hasn't the sensor port, so it doesn't support sensored motor. And the firmware is not updatable.

Is the Xerun 2.0 ESC (not the Sportsman Spec) going to be listed in the ROAR approved Sportsman division ESC list?
