so ive got a 2000w motor and im just wondering whats the maximum power i can run it through? im currently doing 52v battery with 35a controller so im getting around 1800w if that is correct. my 72v 8000w motor on my other bike has snapped so to save the time and effort ordering from china and etc i was wondering if i could fit my battery and the controller to my current bike with the 2000w motor i can limit the controller via bluetooth to say 35a-40a so that the 72v battery gives around 2,500w-2800w. would this work with motor or would i have to limit it to a lower amp to match the motor?

i think im using a display that isnt compatible with my controller as ive had a issue similar to this before, thank you for the help, your explanation defiantly learnt me something and will help others, many thanks

hello and thank you for the reply. so i have 2 e-bikes ive done , and this mentioned display works absolutely fine on my other ebike, displaying everything needed, so i cant have got any wires mixed up so as i mentioned the wires coming out the casing into the connector is not the order it goes, the order was written there, i probably shouldnt have put that picture on as its confusing as it dosent look in order, but just wanted to show the controller wires vs the LCD wire colours, so it goes ; red to red blue to orange black to black green to blue yellow to green so everything matches and works as you've already mentioned but soemthing is still amiss ( and thank you for the extremely efficient accurate description of how the LCD works ) the picture you thought was for LCD is for the controller, the lcd one is for the sw900 and is attached here. so the other display i had on my other ebike, i have now put it onto this ebike and the display is showing watts now but not MPH still . i have the 45a version of this but all cables are the same ; https://cdn.shopifycdn.net/s/files/1/0040/9223/1778/files/36V_48V_52V_35A_3-mode_Controller_Connection_and_User_Manual.pdf?v=1622517260 and this the display im using; https://f.hubspotusercontent10.net/hubfs/7933366/Hub%20Drive%20Display%20Manual.pdf just incase its anything else alltho i cant see it being that reason, i can tell you what other stuff like motor/battery but this problem only risen trying to swap a new controller on. .

i have tried a combination of the green/ yellow cables and ill either get error 10 or 11

ive got the famex ride 2000w 52v aswell, barely did 35 lol. with no load weight ( bike upside down ) it did 44. i had a 1500w with a 35a controller and it was doing 49 mph with no load weight lol. just got a 45a controller so ill let you know when i get it working if it does anything for the speed. do you ever see your watts go anywhere near the 2000w?

hello ive just had a quick search and cant seem to see any other thread with this error. ive got a sw900 display but its a 6 pin waterproof. my controller is a 5 pin connector. ive bought an extenstion for the display and ive connected it up with a 5 pin on the end but leaving the white one out ( wired exactly the same way as my other e bike display ) but its coming up with " ERROR 11 " have to mind the bad wiring it looks as its not in the way it is but as its the first time lol please forgive me but this is how it goes as pictured left to right; red blue black green yellow the controller colours are throwing me off but here is a diagram of whats what. everything works it runs and stops but like mentioned its coming up with a communication error and not displaying speed, watts or anything like that.

thank you very much bud highly appreciated you killed an extra bird with that stone muhc apprecitaed

hello and thank you first of all, i have a stealth bomber frame with a 150a controller on a 8000w motor and i have purchased it off of someone and im trying to upgrade it a little bit. what im trying to do is use the full potentional of the battery and controller by letting it use the maximum amps the controller can give. i think my battery might be 100a BMS, if so then i would buy a battery to get past the 150a controller limit. would anyone be able to tell from what is already set on the settings? im kinda new to this so im learning alot at once, i presume its 100A with the setting already, DC/Boost Current being at 100. but just wanting to be sure and double check before i order anything. many thanks in advance
