Giant Suede controller

:lol: it sure gets me around ok. There is a pot on the board and I was wondering what it did.. I`m guessing that it is the calibration for the voltage cut off?

Just a guess.

The soild bar could an shunt for current limiting.

Unused link could an REVERSE link,
 
I've never seen that model, but on other controllers I've seen adjustment pots for several functions. Possibilities are the LVC, as you mentioned, others are the throttle zero calibration, current limit, and PWM frequency.

It's nice to know what they do.

I'd be real careful when tweaking the pots. The motor could suddenly start.

One method I've used is to carefully mark the original position of the pot, then write down the amount turned (so you can put it back to the starting point). Some pots are multi-turn.

Adjust one pot at a time, slightly, then test the controller to see what changed.
If you can't figure out what changed, tweak it a bit more.

If nothing seems to change, put the pot back to the original position and tweak the next one.

If you raise the current limit, there's a chance of blowing it up under high load.
 
Ahh pot one didn`t give any faster rpm on test but on the bike I notice more "power" on the hills.. I guess as this is the castrated euro version of the bike it could possibly be for the markets elsewhere.. I believe the pot on the side adjusts the pressure needed on the pedelec sensor.

Seems that this the current limiting.

What is most likely to blow then? I do quite a bit of hill work.

If it is overcurrent for too long, FETs are most likely the victims.
