Hi
Can't remember exact figure but approx 50mA @ 48v. So not too many watts.

Rad Modifications / Re: Radwagon 4 motor controller current limit question
« on: September 17, 2021, 11:13:57 AM »
Does anyone know the current limit for the stock radwagon 4 motor controller. It doesn't appear to be written on there and I can't seem to find any info on the internet about it. Thanks

Stock US spec Rad controller is 25A but software limited to 17A. EggRider can override that to 24A.

This "slightly" modified beast does 42 mph on level ground. Speed is plentiful so PAS 3 is often the most used assist level at speeds of 30-35 mph. Torque is enough (for accidental wheelies  ;D).

Rad Modifications / Re: Radpower battery mounting bracket

Where can you purchase Radpower battery mounting brackets? I bought a RadWagon, a Radrunner +, and 2 spare batteries. I want to mount the brackets on the back racks so I can securely carry the spare batteries. Not really interested in the electrical connections as I plan to just switch out the battery when it is depleted.
I more interested in a secure locking method to carry a spare. It really shouldn’t be that hard to get two simple brackets. 😳

Rad battery brackets are only available from Rad. Cannot be found anywhere else.

If the Rad controller does not raise its 750W limit with a higher-voltage battery, there would be no increase in amperage to the motor.

Rad controller limits only amps.

Rad 48V Battery 13s4p Samsung 35e.
Controller is with 63v caps and higher fets.
52V battery is ok.

Almost ready with my custom 60v 24Ah lockable downtube battery. Fitted with 120A/400A Daly BMS. Made of Samsung 40T 21700 cells.


is this something you're developing to sell...or personal mission?

This is something that I wanted to take as personal challenge/project. Not planning to build more as I`m not expert in batteries + lot of work to accomplish.

you are saying rad bikes can support 60 volts with stock display, controller and motor?

Stock motor can handle 60v no problem. The problem with stock motor and wiring is they do not support that much amps. You can concider 25A as "safe" limit. Above risks for failure becomes more evident.
Stock controller and display support max 52v battery.

I have replaced every electrical component on my bike.

Hi

You need Normally open version.

To clarify, if the MT5e model says it's "Higo-Opener" then it's the wrong one? 'Cause that's what I bought and is finally about to arrive ... from Germany...

Thanks.

You need Higo closer, normally open.
Opener is the wrong one.

Rad Modifications / Re: Change cassette or front chain ring
« on: March 19, 2021, 03:28:49 PM »
With the extra speed of the upgraded mini. I find I am pedalling like crazy when 20 or more mph. Would changing the cassette or front chainring to a different size slow the pedal rate down? I would like to pedal more at higher speed in 7th gear. Has anyone tried this ? Any suggestions?   Tony

Rad Modifications / Re: Bafang rear hub motor grease

Getting ready to swap Bolton 750w motor into my Radrover, and have read adding a little extra white lithium grease to the gears is suggested.
Anybody know what grade should be used, or if it matters?
I've found both NLGI 1.5 and NLGI 2 grade white lithium grease.
Thanks

The best best option is Mobil SHC 100 (red). Mobil-28 is also good.
I'm using SHC100.

Thanks. Should I remove, wipe off as much as I can of what is already on there or is it ok to mix?

Better to wipe off most of the old stuff.
