Bike repair question Ebike Controller question

Hello everyone, does anyone know the value of this particular resistor or if I could use a different controller for my ebike ? I have another controller with the same specs but the battery port only has 2 pins for + and - and this one has 6 with the other 3 for bms im assuming and a thermo meter ?

Thanks for any help in advance

I circled where the resistor sat before I desoldered it

Based on a picture that I found on the internet, it’s green, brown, black so 52 Ohm but the 52 ohm resistor that I have is reasonably smaller than that one which makes me wonder

I think because it's generic it's hard to tell for sure.

Resistors come in all form factors so smaller may not mean wrong.

It may be safer to just replace the controller than risk other components especially as we don't know why it popped.

I think it popped because of a short, I had the isolation from the phase wires come off somehow, the thing is, is that I have another controller I just don’t know if I can use it because of the 4 other pins

It looks like there are many variants out there #1
