RegolatoriBL e Guard

[Robby Naish]

Ciao,

stavo leggendole caratteristiche di questo regolatore che evidenzia una sua caratteristica particolare

"Guard 25A Brushless Speed Controller
The Guard series of BESCs have an inbuilt battery cell protector.
By plugging the connector into the batterys charge port the BESC can ensure that the pack is balanced and that the pack never drops below a recomended level. This ensures your pack wont be over-discharged and destroy your battery.
Its the best way to protect your expensive batteries. Considering in most cases your battery costs more than your BESC, its a wise investment to get a guard.
"

Che cambia rispetto al semplice cut-off a voltaggio prestabilito a seconda del numero delle celle?

ciao e grazie

Alex
