is mmm the best one for me?

[timaneli]

hello.
i want to buy a good, powerful and reliable esc and i have a mmm v2 business in hands.

is a good esc or it continues with problems and failures?
can i connect 4 or 5s lipo´s direct to it or do i need to solder a external bec like you people do with the mamba max 1/10 esc?

the esc will be to use on 3s lipo for now but in the future to use on a convert truggy.

regards and any help will be welcome.
