Extreme XB-600

I rode my xb 600 to work today for some real testing. It performed beautifully, except that a co-worker rode it and laid it down :( . Still, fresh off the chargers it runs 30mph exactly, but after a few miles the top speed is more like 28-29mph and 26-27mph on hills. As for the long term, my 72v controller should be in any day and after the shunt mod and another battery we'll see how tough this motor really is. For a 600 watt motor it's got alot of grunt. The bottleneck on these scooters really seems to be the controller. X-treme could offer alot more scooter if they wanted to. i guess everything is limited for reliabilty. I'm looking into a 2000 watt motor in case this one gets melted from 72v LOL.

Hi guys,

I finally got off my scooter and took some pics. I started a new thread showing how I did the 60v mod on my xb 600. Here is the link http://visforvoltage.org/forum/3534-30-mph-xtreme-xb-600-60v-modification-instructions
Thanks for all the help and advice you guys have given me. When my 72v controller gets here, I guess I'll have to make a new thread again! LOL

Here is the link to the youtube video of my speedometer showing 29mph. I had ridden the scooter for awhile so speed had dropped from 30mph to 28-29mph. It happens, but oh well, it's still so fun to ride. Notice how fast it gets to 29mph!! The shunt mod makes it accelerate so fast! http://www.youtube.com/watch?v=N2Sr590DSgw
Let me know what you think.

Found 72v dc-dc converters here for $35 dollars shipped. I have one on order :D http://www.power-factor-1st.com/shop/dc-dc-converter/on-board/sd-15.html

72v chargers...Hmmmm. http://www.evdeals.com/72Vchargers.htm

How are you going to increase the DC-DC converter's max amps up to the 10 amps that the stock converter could deliver (like high beams on, braking with turn signal on)? Also the 72V charger is only rated at 1.2 amps which would take a very long time to charge up. Have you found a 72V charger for a reasonable price that could charge faster? I am watching your progress and potential move up to 72V as I am sitting at 60V on a similar scooter already.

I'm still looking around at prices and options. That soneil charger is the only 72v charger i've found so far. I don't mind slow charging, it's better for the batteries and I charge at night and while I'm at work, so speed charging isn't a big deal for me. As far as the amps on the dc-dc converter.... for $35 I'll try it and see what happens. It's a lot cheaper than the $150 I found on another site. :D
