If all goes well, in less than a month from now I will have a Sabvoton controller installed on my CPX. This and the extra 70ah batteries I have installed on it will make it a proper scooter. Total 160ah batteries that are combined and not the nonsensical one after the other connection.

The Sabvoton controller is able to pull up to 200Amp (compared to the 90 of the original), is able to be programmed to my needs and also Regenerative braking will be available to make it more stable under braking. 

I think it will be a blast and a joy to ride. Range as of now without the controller is estimated at 250km so you can actually go somewhere, and not just 100km city traffic.

very interested in your progress, would love more range on my TC Max and maybe a bit more top speed
