Re: Suzuki GSX-R e899 K2

Too bad you didn't get to explore the true potential of the motor using high voltage and the same current you used at the lower voltage. At least I still have a chance of taking back the top speed with a hubmotor. Of course I'll be doing it with only a 14kg motor instead of a double wide 273. All I ...

Re: Mid-mount Hubmonster Madass

I just have trouble getting past the price, especially since I need 2 per motor. Also, if I am going to spend $700-900 on a pair of controllers, I want high voltage so I can take full advantage of HubMonster. Someday I'll get what I want and run 200V for a lightweight 40-50kw emoto. :mrgreen:

What's the 12v battery for? The point in using a DC/DC converter is to give you a 12V supply, so you don't need to carry a 12V battery. The battery is primarily a backup in the event of DC/DC converter failure. This system is in a three wheeler which is licensed in CA as a motorcycle so the headlig...

Re: My Electric Motorbike

The best way to get better acceleration with any hubmotor is with a smaller wheel, because it's reducing the gearing of the motor which will result in the added benefits of running more efficiently. I don't know how much smaller outside diameter tire will still fit your rim, but even a 10% change ca...

Hydraulic disc brakes may not have as good a feel.

With a 750W scoot I wouldn't haul the extra load, period. Maybe she'd feel more comfortable riding the scoot. Down here a much higher percentage of women ride scooters compared to motorcycles or moto-bicis.

Re: How do I set up a relay for BMS to turn positive pack voltage off

I'm sure there's a way to make it set off an alarm when it trips. The tricky part is to design it so it doesn't add standby drain. If I go audible and light alarms on a BMS trip, they'd be fed 12V by my DC/DC converter that gets power only when the key switch is on. Wouldn't that prevent any standb...

Re: How do I set up a relay for BMS to turn positive pack voltage off

You can power most controllers with 12V, So you can connect the DC to DC Converter to the BMS and you're good to go. Great idea if it works. If not, then I could modify the stepdown to take 12V, which I think is pretty simple depending on type. I'm not sure I like the idea of lights and power shutt...
