I do not think it is a direct replacement look on my website under bad boy and I have direct replacements.
You might be able to make it work but you're going to have to rewire all of the wires or at least most of them and you're going to have to know what's what.
I don't know about what was original, it works, but no power goes 9 mh and tonight had full charge on it and drove maybe 1/2 mile round trip and used 1/2 of battery power
