So, this controller is a real sleeper. I figured that since the output was set at 7 amps, I would solder the shunt up all the way. Oops.
I put it on my bike today and it drew over 100 amps peak at 72v and barely got it warm.
It tripped my 80 amp(100a trip) breaker, so I stopped giving it full throttle uphill.
This controller can be set for 48, 60,72 or 84v just by bridging well marked solder pads on the circuit board.
The self learn function seemed to figure out and re-arrange my hall order without me having to manually switch hall wires to find the correct configuration. It was stuttering so I did the self learn, and it ran smooth after that.
The regen braking is smooth but strong, and quiet.
There is no soft start. It easily pulls up on take off, and at 30mph for that matter.
I bought two more and will buy more, as this is a real hot rodders score. The traces are built up with solder and extra strips of copper.
The only thing is that they used solder with dirty ass flux, and never cleaned it off after beefing up the board. Big deal, it is only visual. Never took pics, sorry.
