I have had a few days now with my XB-508 and feel the $600 plus shipping I spent bought me what I expected. I am happy with the quality of the e-scoot and think it was a good entry level e-scooter. As I mentioned in my previous forum topic (new purchase) my plan was to not spend much money to get a good bead on what is what with e-scooters.My previous ride was a 50cc super bike MX5 motor kit installed on a nice Schwinn 10 speed. My max speed on this ride was 30MPH and cruised at 26MPH. This ride was not real noisy but I grew tired of the noise and stink of mixed gas.
The e-scooter is really a grass roots thing that I believe is about ready to bust open for three reasons; gas prices, battery technology and a new generation of e-scooters available or soon to be this summer. This said if a person commutes around 10 miles or so each way and can live with 40 some miles per hour the e-scooter makes perfect sense. I say this because 50MPH is asking a lot from available technology and running a lot more than 10 miles a trip with current battery technology uses up the life of a battery quickly amounting to big $$$ to keep an E-scooter performing at high speed for any good distance.
Thanks for indulging me in my thoughts. Back to my XB-508 my whole idea behind even messing with the XB-508 was to make the smallest investment I could to get something to experiment with and not feel bad if I burn it up. I plan to upgrade to something in the 40MPH club after I decide if a $1500 XM-2000 is good enough until the next generation e-scooter and batteries are here. I'm also considering a Z-20 or a ZE-2000. Understanding physics and some sense tells me 50+ MPH is always going to require a lot of power.

Re: X-Treme XB-508

On my XB-508 I pulled some things apart and found there is a 30amp fuse between the battery pack and controller. I'm guessing this means the controller pull less than 30amps. There are a lot of things I don't know about the controller and my efforts to take it apart to gain some knowlege about it failed becase it is glued (potted) into its aluminum inclosure. I may try adding a fifth battery in series to bring the power to 60volts. I don't know if the controller will pass extra voltage to the motor. I understand most controllers pass less voltage to the motor than the batteries supply. This means a 48volt system doesn't get 48volts to the motor and a 60volt system could deliver more than 48 and less than 60 to the motor.
Any body have experience with X-tremes controllers or understands controller basics enough to tell me if a 60volt mod on the XB-508 could work?
