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

[Chris]

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.
