T-Ray Posted April 13, 2023 Share Posted April 13, 2023 I bought a second hand kingsong 14M 2 months ago. I paid almost 200 USD. Its mileage at the time was around 25km. Been learning and using it and found that its top speed of 20Kph is just too slow for me. Would it be possible to upgrade this unit by adding another 210Kw battery pack? The device details found in the app and in the wheel are as follows: Tyre/Rim info: KS-14-ZX800W22051600456 Device info: Battery Cap:210Wh Model:KS-14SME Firmware ver:V2.12 Current firmware info. battery high temperature alarm russia ADC sample just support batvol manu just KS-14SME for GD32 compatible This unit also comes with LED lights on all four corners. It has the speakers too. Has anyone ever succeeded in upgrading their 14M into 14D ang gotten the range extended as well as a speed bump from 20Kph to 30Kph? If yes, can you please give me the step by step on how it was done? 1 Quote Link to comment Share on other sites More sharing options...
Galbekan Posted July 29, 2023 Share Posted July 29, 2023 I'm also trying to have this sorted. Bought the M version because the law here limits EUC's to top speed of 20kmh (from factory), but I wanted the extra range (and speed, if possible) of a new battery pack without risk of setting my little guy on fire.
