Hey all,
I've adapated a 52v battery to my RadRunner 3+ (everything else stock - display, controller etc). Display turns on but I get no ppower to the motor from throttle or peddling. Do I need to change the stock controller?
I am pretty sure your stock controller is only 25 watts and has a max of 52 volts. The battery you added is probably max of 56 volts and the controller can't handle that much. So yes you need a 35 watt controller as it will handle the new battery but I am told it will not a 60 volt battery.

Area 13 sometimes has them in stock. They are good for a source of information and troubleshooting as well. They do respond to email but sometimes it takes them a few days.
UPDATE: I got the https://electrobikeworld.com/products/rad-power-6-upgrade-kit and this worked juust fine on my RadRunner 3+. Stock 500w motor is happily dirven w/ either the 48v or 52v battery.

I think Rad called some Bafang motor 750 watt when that may have been the peak wattage. I have seen some YouTube videos of putting a real 750 wattage Bafang in Rad Mini 4. In a side by side comparison there is a significant size difference.

Ah man really? Bleh I think I'm still gonna get the RR 3+ for the wifey though. Was just hoping not having to swap the motor
