I purchased a 48v/22A controller from JN (DC Moto Controller by Lithium Battery) that came with an S900 display. After 1 month of waiting and hours of getting it into my bike, I see the S900 display limits the current to 20A. I see that JN also sells controllers that go up to 35A and they use the same displays. I looked up every display compatible with JN controllers that they list on their seller page and they all have a current limit of 20A in their manuals.
I do not understand this. Are people actually buying expensive 35A controllers with displays that limit them to 20A? or are there sellers that sell displays with modified parameters that remove the current limits?
My bike controller compartment has an odd shape and so it took a lot of time, effort, soldering and even filing, to get it to fit (2 days of work). I really don't want to undo all of that if I can avoid it. Also, I already spent $1600 on this bike, $100 on panniers, $60 on spare parts, and $100 on a controller/display replacement, if I spend $80-$100 more, my wife might kill me.
I tried a KT LCD3 and an S866 display on it from my other bikes. Display comes on but no throttle/lights. So not compatible.
Are there any sellers that sell modified versions of displays or displays with higher current limits? Is it possible to bypass the display current limit via modifying firmware or other methods?
I'm pretty annoyed by this tbh. If I pay for a 22A controller, I should get 22A. If I wanted a 20A controller I'd have bought a 20A controller and not have had to spend hours getting it to fit. It is my fault for not looking up the manual before purchasing, but I wrongly assumed that if I bought a 22A controller, I'd get 22A. As a side note, it's also not showing watt output for whatever reason. Maybe a loose wire somewhere but I don't have the mental strength right now to take it back apart as it was painful getting everything into place.
