i just installed 12 led setup on my mt4g3 ,
it works fine and everthing,
4 on the front with throttle and 4 on the back with brake and indicators front and back with steering when turning left and right,
but i need to know if i take it out using 6s or usual 4s,
do i need to use external bec or my hobbywing 150a esc's builtin bec is adequate to supply the power my mt4g3 needs?
cheers, guys
