Looking for Surron controller

Hey...I dont know how I did it, but I reversed the positive and negative leads on my Surron controller, and well..the leads on the end of the battery burned right off.....
I can save the battery but BMS I assume is fried..and controller..funny the breaker did not work..anyway..After buying a BAC 4000 and not being able to make it work, im looking for a Surron stock controller. If you have one and its working, let me know..

I dont know how...but after repairing the battery pack

the controller still lives!!..that's a robust unit!!..BMS is fried but I can install either a new one or source out another and install.

Thanks to everyone.
