KT-3 LCD battery flashing, new controller

Hello evryone,

I have a 48v 1500w kit installed on my bike. I was running with a 48v battery made by me for more then one year.
I recently upgraded the battery and its now 52v but after few minuts of riding my bike just stoped and shuts down plus the electric wheel was stuck in regen breaking. After investigations it turn up that the new battery burned the old controller.
I got a bigger one for 60v now but after installing it there is a problem. If I try go to electric it cuts off after 2 seconds and the battery lvl flashes empty and doesn't work. If I restart the display the same thing for 2 seconds. My display is the kt-3 lcd. I will put a link o youtube with the video that I made https://youtu.be/qUdrL3vN5xw

Any ideas why?

Do you think it's possible that you damaged the battery's BMS in addition to the old controller?

I have my old 48v battery and I tryed couple batteries and the same. I changed the controller and now its working
