S-LCD3 purchased from BMSBattery.com
Step 1: Attach LCD3 to handlebars
Step 2: Snip off the useless white flat 5-pin connector.
Step 3: Pull meter cable through top hole in sondors battery box. (no picture)
Step 4: Snip off the round 5-pin female plug and strip all the wiring down a half inch.
Step 5: Proceed to tin the stranded wire ends. tinning means to apply hot motlen solder to the stranded wire, which helps to solder two separate wires together.
Step 6: Admire your soldering job and apply insulation. I used cheap electrical tape, but you should spend a few cents and get some shrink tube.
Step 7: Double check that no exposed wire is showing, and test our your new lcd meter. Hold the center power button to turn on. To keep the backlight on for easy viewing, press and hold the up arrow. If you hold and press the down arrow, your bike will lurch forward at a walking speed, so be careful!
Q: I press and hold the up arrow like you said and my bike wants to go for a ride. What gives?
A: You installed your LCD button upsidedown. Reverse it and you should be fine.
Q: Halp! Why is my LCD screen upside down?
A: You installed your LCD screen upside down. /reverse it and you should be fine.
Q: After installing the LCD, I am unable to engage the throttle and the bike does not move, yet everything is on. What Gives?
A: Check that the LCD screen is actually on, you must have the LCD turned on in order for you to power your bike and use the motor.

My lcd has just died on my Fold sport from water damage I'm quite sure so this is my perfect opportunity to upgrade I have been looking at the 750w bafang rear hub motor and they say it will lace in 350w motor no problem but I have the 250w bafang rear hub motor. Will it fit? But first I want too upgrade the sondors lcd to the ktc3 25 amp and 25 amp controller and will wait till sondors have the 48v 14 amp available in Europe until i upgrade the motor as the 38v 8.8amp battery won't be powerful enough. Any suggestions or problems with my plan I would appreciate feed back

Hello everyone, I currently have an Original Sondors Fat Tire bike from 2016 (I believe). I purchased it from a friend who had performed some upgrades to it.
As the bike sits today:
Luna Storm 48v 20ah Battery Controller Model KT36/48ZWSRMD-SLSLD02 Rated for DC 36v or 48v, Rated current 12A Maximum current 25+-1A (Assuming this is from Luna as well) Original Motor Bafang RMG06 36v 350W(10) 26-1-1508195560-6 LCD Luna LCD Dashboard for Sondors KT-LCD3 Took the bike out for a ride the other day after it had been sitting in the garage for about a month and received a motor hall connection error on my LCD screen. Tried the usual unplugging the connection under the chainstay and making sure I had charged the battery. I'm wondering if I am able to replace the cable coming out of my motor (if that is the culprit) or if I need to replace the motor altogether. If that is the case, would anyone recommend I upgrade to a 48v motor? Would it make a difference/ work with my existing upgrades? I'm new to the forum and Ebike scene in general so I appreciate any help. Thanks!
