That depends on if you race or play.What's sorta of funny is I own an Integy 16x9 and I want to get an upper end charger,dont get me wrong the 16x9 is a good charger but I want to get a charger that has a motor break in feature(so I can run my com. lathe)In a charger you would want one that charges at least 6 amps.can cycle,the more you pay the more feature's it will(or should)have.I know that it seems like a waste of money but in the long run it's not.
