Need Battery help (got none on BenHeck Forums)

[Sonic4freedom]

Okay, so I have this battery, a Li-poly, its a 7.4v 5000mAh 15C Li-Po Battery for a(n) RC car. Now I need a charger. This battery has a 3 prong connecter for charging, so I comprised a list, just tell me which will work and what would be the best, thank you
