[NSRCA-discussion] E-deadstick, trouble-shooting.

Thu Jun 9 13:11:51 AKDT 2011

Hi Chris, 

That is correct. I got CC just few blocks from home. Just went there and they got it fix. Very nice guys. I am not sure if the problem below could have some relation with this setting. Probably not but just in case.,

A Castle Tech told me that we want to set the current limiting to "insensitive" to avoid any false cut outs caused my momentary voltage drops. Along with that, you should hard set the cell count via the min voltage to 30V for a 10S setup. This has worked for lots and lots of us for many years with the Castle controllers.

I don't recall how CC call it. There is a setting for current slope or ramp. If you have it too sensitive the controller could shot down when you power up the plane in long vertical maneuvers. I didn't follow all the e-mails but this happen to me one time with a CC controller.

The losses(heat) is not only dependent on current (I2R) but also Mosfet switching losses. V(in) is a factor in the equations.

FWIW - I have the CC Ice HV 80 in an Integral, and the data logger 
typically shows the temp rising to around 140-150F (60-80 amp draw) 
and hovering there for the entire flight. Castle tech support says 
that their controllers don't start throttling back the juice until the 
internal temp reaches over 200F. 

What I find interesting is that I have the same controller on my 
Osiris (5S pack vs. 10S pack) pulling the same 80 amps, but the 
controller temp only rises to about 90F on the Osiris. 

I haven't downloaded the data from Andersonville , but I didn't see any 
power loss all weekend. I'm sure that if the system was going to 
overtemp , it would have happened this last weekend.
