I haven't bought this scooter yet, but I'm almost certain I will within the next day or two. I found an Internet source where it's on sale from for $2350 + $200 shipping!
For me, the prospect of going 50+ MPH would be great for taking the occasional trip on the highway to the next town 11 miles over. The XM-5000li could do this natively, but it's way too expensive at $5500 when I can seemingly buy and upgrade an XM-3500li for a little over $4100.
- So, from those who know more about the subject, I'd like to know if I can add the Kelly 6.0KW brushless hub motor upgrade? Also I'd like to confirm I'd need the 13-inch size.
- Of course I would need the Kelly 150A brushless DC motor controller to match the power requirements. I noticed it has regen, but how have people tied in the regen? Another regen-break lever? Are the brakes cable-driven like on a bicycle, or are they electronically controlled?
- From there, I would like to add four more of the 40ah Thundersky batteries. Is there room for these, or would this require a frame modification? I've seen people posting about having 8 additional cells, but I haven't seen anything on how they fit them.
- I'm looking at the 24-cell BMS from Rechargeable Lithium Power, but what charger should I be looking at? Also, does the DC/DC converter need to be replaced, and if so what brand should I be looking at?
Finally, is there anything else I should be considering?
My pricing so far:
XM-3500li Moped + $200 shipping = $2550
6.0 Kelly brushless hub motor upgrade = $599
24-120V,150A, brushless motor controller = $499
4 additional 40A Thundersky batteries = $256
24-cell BMS = $230
DC/DC converter ???
Smart charger ???
For a total of $4134 + some shipping. That seems like a steal to me compared to the premade scooters out there!
