Does anyone know what controller this is? And, will it handle a 48v battery?

It is in the Tigershark battery small controller case located on the Kristall E5 36v/250w hub motor ebike. The LCD screen the controller connects to is the G51.

I have had a controller die after it was in an accident.

I have other ebikes with this controller. And, looking at building 48v batteries for them

Thanks for your help.

I found this by searching "808504 controller" on Google images you'll find a picture with the same board markings. It looks to take 48v. I hope this helps

According to the specs on the bike, it's a: "5 Shifts intelligent IC control system"

I noticed that if you search on that, there are a bunch of AliExpress ebikes that use that controller.
 
Thanks everyone for your help. I will see if I can purchase another controller.
