Phraggle

So,i have the old Msuper,1st gen. It was my first wheel,and i have kept it as a loner wheel. I lent it to a buddy for a few months,and it just recently it stopped charging. Had an electrician friend take it apart and have a look at it. He chased all the wires with a meter,and found a circuit board on one of the battery packs was where the problem was. We didnt want to un solder the board,that felt a little beyond our skills and tools at the moment. Is that something i can order from Ewheels and either install myself,or find someone near me that can,or should i just buy a whole new battery pack with the board already installed? My electrician buddy told me the battery pack seemed good,but suggested replacing batteries and board together,what are your suggestions? Also...is there a possibility of using any or most of the components of the old Msuper to piece together a safer,less unpredictable wheel( this Msuper cut off on me at 20mph and hobbled me for 6 months!)?

@benkim Out of curiosity, how much?

Hmmm,i guess i liked the ks18s for the 28 inch height with seat,seems weird that the smaller ks18xl has the 2000w motor. I like the idea of sitting,which is why the ks18s was appealing , not that I've tried sitting,I have an old msuper and a ninebot one E+,but the taller profile intuitively makes more sense for sitting to me. The appeal of the msx is the offroad capabilities, higher speed,higher pedal clearance,better hill climbing. Truthfully, the ks18s's height and seat combo were what sparked my interest,that and larger pedals and being able to set incline on them,mostly for long rides,that's pretty much it,oh and durability. Otherwise,the msx is probably more suitable for my needs. BT speakers are novel,but not a necessity. The seat on the squat msx doesn't look like a natural or comfortable ride,but everything else about it besides the flimsy shell sound like what I want. I did wreck pretty bad on my msuper a couple of weeks ago due to cut off at 20mph, and am still hobbled by it( mangled my knee,broke 2 toes,dislocated my shoulder and LOTS of road rash), so safety all of a sudden became important. Also,the wreck did sheer off some screw holes on the msuper. I still can't ride,I can barely walk,so I guess I have a little more time to choose. I have the money and have been peppering poor Jason from ewheels with a litany of questions and emails,so I want to order soon so he doesn't think I'm stringing him along and make it worth his time and patience! Again, I'm most likely going for the msx, I'm just having that last minute waffle and wanna give the ks18s its final chance,maybe something I didn't know might pop up,maybe I just have cold feet,either way I appreciate all your input and help.

I'm about to order a new wheel( likely this week)from Ewheels, I'm pretty certain i want the new MSX,but for a bit there,the KS18S was seriously in the running. I just wanted to do one last glance back at that possibility before I put a ring on that finger. I've watched all the comparison vids I can find,reviews etc.,but I figure some of you have one or both,and can either confirm my choice,or cause some last minute reconsideration.
