[NSRCA-discussion] Hacker ESC programming

Fri Aug 3 13:43:10 AKDT 2007

Try Dimension Engineering also

I'm pretty sure they make a lipo cut-off that will detect individual cells 
and go by the low one... and also ballances the battery in flight...

And some of the high end ESC's are starting to have in-flight battery 
ballancing + cut-off based on voltage of the low cell, not the whole pack.
