54/60V Battery or True 750W Motor as the next upgrade?

[FortunatelyTheMilk]

I've got a 2019 Rad Runner, with about 5000km on the stock battery and motor.
I've been running a 35A Controller for about 60% of that.
The battery is beginning to show its age, my napkin maths reckons it's down to 60% SOH compared to when new. Range from full is about 40km, wit a 50/50 mix of PAS1 and 100% throttle.
I'm considering replacing the battery with a higher voltage pack, and at the same time I'm wondering if I should just go ahead and upgrade the motor to get the most bang for my euro (assuming the stock motor goes bang if I don't upgrade it! ).

Higher top speed is the goal here, rather than acceleration (which is more than enough with the 35A brain!).



Has anyone run the 35A controller with a higher voltage battery pack?
Are there other higher power or higher KV motors available that are compatible with the 35A controller?

I know about the "true" 750W Bafang upgrade, and I've just seen some videos with a 3000W(!) motor, but that looks like a risky AliX purchase...

That 35A controller is 52v battery max. I do sell 40A  controller kits capable of 60v (17s) battery for G062.1000w motor.
I have my Rad modded 60v 64A with modded G062 motor. 42mph.

The G062.1000w motor is a good one, and JTK77's setup is probably the best way to go. I bought two of those motors from AliExpress with no issues. You will need to re-lace your back wheel to install this motor, but totally worth it IMHO. I had the so-called "upgrade" motors from Bolton. All four of them failed. The original Rad motor handled the power better.
