Good evening i would like some advice pls

[Bikenovice]

I have a volt alpine which I consider my mobility scooter I have owned it since 2013 a new battery cost 340 pound so I bought a mid mount from China which I am hoping to run on my cheap Chinese battery but I have looked at the bottom of my volt battery and I can't see a + or - just four pins coming from the base of the mounting plate my hope is to connect a four pin female plug and run it of the cheap Chinese battery any help will be appreciated
