vasuvius Posted January 23, 2020 Share Posted January 23, 2020 What's the difference between 14D and 14SMD ? Where can I look up specs for the 14SMD ? Quote Link to comment Share on other sites More sharing options...
The Fat Unicyclist Posted January 23, 2020 Share Posted January 23, 2020 It's not quite like that... King Song make 3 different 14" wheels; 14M - no BT and only one battery 14D - with BT and two batteries 14S - with BT and two bigger batteries Basically they are all a 14D, except the entry-level 14M is a "stripped back" version and the 14S is a fatter version (to fit in more battery cells). The key point is that they all use the same control board, which is subsequently named 14SMD. 1 1 Quote Link to comment Share on other sites More sharing options...
vasuvius Posted January 23, 2020 Author Share Posted January 23, 2020 Hmmm. In the app I see Model: 14-SMD Name: 14-SMD-0109 Serial Number: KS14D******* It has BT. Is this the one with 2 batteries or 2 bigger batteries ? Quote Link to comment Share on other sites More sharing options...

Is this the one with 2 batteries or 2 bigger batteries ? It's a 14D, which would mean your battery capacity is most likely 420 Wh (though there is a 340 Wh version too). The 14M is identical to the 14D, but the 14S is noticably different - rather than smooth sides, they bulge out as there are literally twice as meany cells inside (giving a capacity of either 680 Wh or 840 Wh). This is a 14D (or 14M): And this is a 14S: I'm sure you will be able to confirm which model you have from that. What you can't tell looking at the 14S images is that the pads aren't any thicker - other than the top third the padding is only about 2 mm thick as the plastic of the shell extends outward to make room for the batteries. The motor and control board are the same in each. And (other then the physical aspect), the only differences are that the 14S has more available power (as sometimes needed by Fat Unicyclists) due to having more cells in parallel and also more range. 1 Quote Link to comment Share on other sites More sharing options...
vasuvius Posted January 23, 2020 Author Share Posted January 23, 2020 It's the 14D then with the 420Wh battery. Thank you for educating me. Quote Link to comment Share on other sites More sharing options...
Seba Posted January 24, 2020 Share Posted January 24, 2020 I may be wrong, but KS-14SMD is a unified firmware for wheels with newer controller board variant that is common to all three models. Still, exact model name and battery variant is encoded into serial number, so firmware "knows" remaining hardware and behaves accordingly. 1 Quote Link to comment Share on other sites More sharing options...

noduh Posted December 13, 2020 Share Posted December 13, 2020 There is a difference with the fuse also, it used to be accessible under the USB port, but it's now hidden. 2 Quote Link to comment Share on other sites More sharing options...
