hvmaxx with cc bec ?

i have decided to get a e-revo roller and i will be sending in my hvmaxx to be exchanged for a new version with a 6.5 motor for good old fashioned bashing, would running a external bec help to maintain lower esc. temps? it will be geared very low for fun and runtime but my thought is it wont hurt to run it, it can only help right?

i knew i should have held onto my esc. and motor

oh well


thanks for any help
