What? a 54xx? Not unless someone sells theirs, as you may or may not know they were a special order
Next bedt is 5304 ?, try Ed Lyen

Or go one better and get the Cromotor from Methods

So hooking up my 5404 to one of cell_man's new 24 fet controllers he sells. It's solid and looks like the other 24 fet's I have seen.
Actually opened up the end last night and peeked inside - traces seem pretty beefy and it's rated for 90 amps and 80 something volts I think.
Anyway about to start doing my favorite dance and that's the phase wire / hall combo one.
I know the lyen to crystalyte combo's so I think i am going to just go with that.. doing some searching so far not able to find anything
definitive as most people in the past use cell_man's controllers with mac/bms or mxus motors supplied by him.
Worked it out - just looks like standard crystalyte-infenion colors.
