MGM article on voltage under braking & lipo quality

[othello]

I found a better graph i posted some time ago (while i was running 10s1p A123) where i pointed out braking Amps and the corresponding rise in voltage. The green curve depicts motor rpm.



@BrianG
When opening the eagletree logfile with excel you won't notice any negative value. There is no way you can differentiate between amps flowing to the motor and amps flowing to the battery when using an eagletree logger (other then looking at the voltage).

@zeropointbug
The Kontronik Jazz 55-10-32 ESC is rated up to 43V (10s lipo). With 8s A123 (25V average) i'm well below it's rated max voltage leaving enough headroom for braking voltage spikes. Even with 11s A123 (36v average) i do not have issues while braking with the ESC. I too tend to run my ESCs below their rated max specs to avoid premature failing.
