Feedbacks and suggestions from our valued clients lead us to touch up the topic to oursw900LCD displays.  Customers have a choice when they buy a kit from us to choose LCD display from the display options.  One can encounter tons of LCD’s but particularlyebikelingkits use this model. Obviously updates and changes will follow our LCD display options but as far as we go we will be utilizingsw900model.  Let’s look into simple but important details and instructions ofsw900LCD display.

Things like the color of the wires, dimensions and other deep technical details excluded because we think these are not the major problems that concern clients most.  Overall display is in rectangular shape and black in color with the6ftlong wire connector.  This is pretty long to wire up your bicycle.  Screen divided into smaller6 portionsand display has at most3 buttons. Looks simple? But that few buttons will give thefunctionsthat most ebikers need.  On/off button shuts off kit completely, which means you don’t need to worry about if your battery damaging the controller while your electric bicycle on rest.  If you had on/off switch on your battery it’s always wise to off the display first and battery but when turning on vice versa.  Again 6 levels (0-5) ofPAScan be manipulated through display by just clicking up/down buttons on the main menu.  And other background luminescence, wheel size 6km/h cruise control, voltage and max speed settings can be changed from here by just pressing buttons in different ways. One thing to keep in mind if thecontrollerdisabled speed limiting option from the manufacturer, it may not be possible to limit speed from display.  For convenience, we will include display instructions on ourmenu. Please check it whenever you need manual to ourproducts.

One more important thing point out here is thatsw900LCD displays are not % 100waterproof. Connecting points may leak water inside if it’s left outside for heavy rain, for long time.  Wrap, tape can help to close the source of leak.

What are the differences between these twoelectric bikedisplay types and why should we prefer LED or LCD? What additional features does an LCD display offer us? Why should we pay more? These are the questions most clients ask when it comes to choosing a display.

The 810 LED display offers the features mentioned above. It serves its purpose and does not have extra features. It is solely there to make the eBike function.  If you do not require anything else and want a simple display with basic functions then the 810 LED Display is exactly what you are looking for.

The SW900 LCD display offers much more than a digital screen and fancy look, it allows users to editcontroller parameters, control all functions on your ebike from speed to wheel size and even an external headlight.

Which do we prefer? We certainly recommend an LCD display if the client is using their eBike often and therefore taking advantage of it’s extra features everyday, whether it’s commuting to work or enjoying a casual ride.

Needed a controller for testing so bought the only controller with connector for a display that I could get quickly (surprising how difficult/near impossible it is to find controllers sold alone that have a display cable. But, found Wal-Mart has a GREAT listing of controllers, better than eBay, Amazon, Sears, and Aliexpress combined, 100s of them! Check it out. I"m also now aware you can add a display cable to almost any controller because most have the signals on the PCB. Might be useful to someone.)

Anyway, bought an Ebikeling 36/48V 500W controller (yes, I know 22A capable) for use with 36V 10Ah batt, 2014 LCD 3 and Q100 (yes, I know 12-18A max by tinning the KU65 shunt.) I attempted to turn power down by setting C5=3, or so I thought; and therein lies the problem- that"s BMSBattery C5, and ebikeling S830 LCD display manual doesn"t even mention C settings

Regardless, the ebikeling 500W controller drives the Q100 smoothly on throttle, both sensored & sensorless, and they even work in pedal assist... except PAS is set to 0 in the display (hmmm, 1st clue: PAS shouldn"t work at all if PAS=0).

Here"s the big clue that controller & display aren"t communicating well: LCD 3 display shows 41V in lower right corner (which must be an AD measurement inside the LCD3 display), but MPH, battery icon charge level, W, and battery temp are all blank on the LCD3, and I assume all 4 are controller values "transmitted" from the controller to the display. (Yes, I"ve checked pinouts: swapped 2 sensor pins in the Hall plug which made the Q100 run sensored, and everything else aligns.)

Would someone please validate this logic & correct me of I"m wrong: the old LCD3 display and this new ebikeling 36/48 500W controller don"t communicate well if at all because the LCD 3 display only knows parameters P1-5 (P5=15 of course being 36V voltage level) and the ebikeling controller expects an LCD 830 display and communicates P1-16, e.g. requiring "P03 the parameter to set Voltage Class: 24V /36V / 48V." (P3 for the LCD 3 is PAS mode, 0 or 1.)

Bottom line, I assume the new controller is defaulting to "48V battery" and therefore even 41V full charge is empty, which it "transmits" to the display, if any data is sent at all. Controller probably sends mph, temp, and power, too, but the 5-parameter KT LCD 3 doesn"t understand the 16-parameter data stream.

I have searched battery icon blank, Ebikeling controllers etc, but nowhere did I find a mention about 16 parameter controllers, nor about differing parameter sets being a reason for non-communication, only incompatible displays & controllers. And, I"ve seen lots of discussion about flashing the LCD 3 to work with the TSDZ2 & Bafang MDM"s internal controllers, but nothing about making it work with other controllers.

Yes, I"ve read as many of Amberwolf"s posts on empty or half full battery symbols as I can, but nothing regarding parameters/ comms mismatch. I"m now starting to read casainho"s posts on flashing the LCD 3, but I gather it"s all in reference to the TSDZ2.

Suzhou KUNTENG Electronics Co., Ltd. is a specialized factory focusing on design, development, production and sale of electric vehicle controller, display instruments, sensors, corresponding products

So, same as at my company, there are probably ten or twenty hardware & software engineers sitting in a space together, all designing and programming similar but slightly different P parameter and C parameters and values for all their customers, with slightly different connectors. And they could probably make any one controller talk to a certain display. They"re simply software and memory upgrades. I "simply" want to know how to do it if possible.

Comparing my 2014 LCD3 P & C parameter lists to new S830 & SW900 P parameter sets, there"s very high similarity. Some Shenzhen Kunteng engineering manager probably asked, "So, why do we have 2 parameter lists?"

Then he tasked an engineer to simplify and merge the P & C parameters into one P parameter list, obsoleting some old displays, and creating new sales opportunities. Now the question is, how do I access the new list via the old LCD3? For example, when controller asks for P03 (24V, 36V, 48V) convert and send P5. When controller sends Watts value place it in the W window.

It"s the same thing they did with adding one (yellow) wire to 4-pin LED 810s several years ago, they made them 5-pin 810s, 880s, & 890s...so they"re minimally programmable and compatible with all 5-pin LCD wiring connector.

If three or four of the major motor companies motors often work with either LED or LCD 5-pin displays, then all of the 5-pin displays most likely share the same communications protocol. The difference, then, is the P & C parameters and the order in which they"re sent& read.

I read a very good article showing how to sample the serial line to be able to view controller data in the eBIKE display, by ebikebuilder1. Similar 16 parameter output as noted above.

Searching around, it seems Shenzhen Kunteng makes a large percent of all small EV controllers as well all the LED 790, 810s, 880s, 890s, all the LCD 3, 5 6, 8, 830...& 900 displays.

Bought my daughter an ECOTRIC 36v 350w geared hub ebike with 810 controller, the pas was 12mph min, instant on on setting 1 of 3 and very for her hard to use. Swapped its 19amp controller out for an ebikeling 36v/48v 22amp and a 36v/48v sw900 (from ebikling) and the ebikeling sw900 and wow what a difference. Very nice smooth operation. I set sw900 pas sensitivity to 5 (lower is more sensitive despite sw900 instructions saying the opposite) and set pas ramp to 2 of 5, 36v and amps to 19 (to limit the power to match factory controller, battery and hub). It seems to spike peak to a bit over 800w ish with my 280lb and pas 5 but my daugher is much much ligher. Very smooth operating controller and display. My 8 year old has no problems riding the bike now. Took some fiddling to get speedo sorta correct with p7 settings. Power is limited and comes on with a smooth ramp. Throttle power is limited to each pas levels max which is nice. Replaced the throttle with a half grip type with an off switch so we could set the sw900 to have pas/theottle on but only use pas unless throttle was needed (pas 0 shuts off both). Took a few hrs as as I had to swap some plugs and get it to fit but great value (own 2 other ebikes a 2500w 50amp and 250w 15amp).
