Hi everyone!

I have a 48V Battery that I lost the key for. I opened the battery ,uninstalled the lock but having trouble with the 5 pins inside and where what goes.
The one one the middle is not connected i think. On one side is 2 plus sockets and on the other 2 minus. The battery has 2 big cables for power and 2 more...
I have soldered the ground cables together on the 2 minus sockets and tried the 2 plus poles separately and soldered together but the battery wont charge. It works in the bike but just won`t charge. Any ideas what I`ve done wrong?

Thank you in advance!
