Maybe you did not read the whole tread, but i have 21S of 50AH Lithium-Ion (3,9KWH nominel), not SLA.
My apologies - was hard to see the whole context on the phone.
21s - must go pretty quickly!

Yes, its quick ;)
Pushing 90+ km/h and it gets there very fast.
Quite happy about it.

I also ordered an new rear damper for it, should arrive sometime next week.

Any improvement to the suspension is going to be noticeable right away.

The rear suspension is now perfect..

This winter i will take apart the front suspention and try to find some softer springs to fit.. the front is way to stiff.

Interesting thread, I have an E-Max 90S with a broken motor controller, since it is the same type of epoxy covered design as in the pictures in this thread it is very hard to examine it and try to understand what can be wrong with it.
I have had very little luck in finding any information about the original motor controller on the internet, but the schematic in this thread is very interesting information and should make it easier to replace it with something else.

Did you find out everything you posted in this thread by reverse engineering, or did you find some documentation somewhere?

The manual you attached offpist1 mentions an LED code reference table, but it is not included in the document.
My controller does flash some pattern on the LED, so would kind of be interesting to find out what it means, in case the problem is actually external to the controller...
So if anyone knows about those codes, please let me know.

Otherwise, well, for the right price I can perhaps be interested in the original controller, do you have any idea what you want for it?
I was originally thinking I wanted something more robust and potentially better performance, since it seems from what I read that these controllers break quite easily.
But of course just replacing it with an equivalent is a lot easier...

I am not interested in another complete scooter, actually I was not planning on keeping mine either in the long run. :)

Great, thanks.

Interesting, mine is blinking 6 times.
Which either is "Scooter disabled", whatever that means (it does say "Vehicle disabled" in the instrument cluster display), or side stand out.
As I remember it when the side stand is out, it displays a message more specifically about that in the display, does it not?
