2015 Raleigh Takoa iE Battery Advice

[bernard17]

I have a 2015 Raleigh Tekoa iE bike but with no battery, just the wire w/ 4 ends coming out of the frame. It is a beautiful bike. I never owned an e bike before and want to be sure to get the right battery for it. I do know it was a 48v 10 ah battery 500 w motor before, but that is all I know. I have looked on Amazon and a few other places but they do not show the area where the 4 prong plug from the frame goes into the battery harness or whatever it's called. I want to get the proper battery and all that goes w/ it to be sure I don't ruin the electronics. I would appreciate any and all advice to get what I need to have it back to the way it should be. Thank you.
