This is not the lack of quality control this is the absence of quality control 😂😂😂

IWanted to see bottom of that one. Having trouble matching old
one, has what I
think is better
current flow on
raised bar material.You put it back in box without a
look but I got a glimpse. But mine is got more circuits with the high flow looking top secret shit
you cain't get
information for.
I don't what to call what I said.
If you could point me in right direction it would be apprecated. I have a fiido T-1 cargo 20Ah 48v
750w looking for controller as good or better. Thanks

im checking mine when it shows up, sometimes you look for a deal but you end up getting scammed.

You didn't do the self learning cycle so you when you gave her full beans there your phase offset hadn't been set yet. It's the two turquoise wires and they're marked as 6/12 on the board.

[@karmaEbikes.]

phase was fine.

[@sofa-kingfpv3295]

And the fers are marked that way cuz there are positives and negative fers that's why your seeing them alternate but with 1 then 2 repeating Three times as there are three phases.

[@karmaEbikes.]

non of the fets are marked. just dirty with finger prints from repairing it in a hurry. ill try to show that in the next video.

[@petrolpete100]
