I see half a dozen wires coming out. I think I know why.It's not the 18650 based design but that awful IMO flat Lithium battery pack.
The picture does show us the - and + marks which line up nicely with the black and red wires.So, there's your connections to the battery and 99.99% sure to be where to hook up a charger.Now this is of course dangerous as batteries like these can go up in flames so if I were pressed to find a way to charge it, here's the charger I would try charge this 7.4V LiPo battery.Try red to red, black to black and white to white.
