Perfect!!!
Works as expected on my Rad Expand 5. I didn't use the default settings as they are too aggressive.

35 Amp Controller Upgrade
I’m very pleased with my experience with the controller upgrade. I can now go up hills with ease that we’re a struggle for me previously. Installing the controller was much easier than I had imagined it would be as all of the connections were different sizes and different colors. Also, I am still getting good range on my rides. Previously I could go about 33 kms. on a ride and now I can go 28 kms. which is acceptable as far as I’m concerned. My C5 is set to 7 and that is plenty of power for me.
The display is very easy to read in the sunshine compared to the last one! That is a big plus for me as my vision is not great.
Thank you affordable E bikes for your great price on this upgrade.
Happy writing, Tony
