I have a imax b6 charger and I love it, no complaints about it what so ever, I even got the imax ac adapter so I can charge inside the house too. Its also a very easy to use charger that has alot of safety features on it too, plus it charges A123 cells too, not bad for a $65.00 charger.

I have zippy-R 4s 4500mah and zippy-H 6s 4000mah packs both packs deliever solid amps and work fine charge after charge. The only thing you have to worry about with these packs is their size as they are meant for airplane useage. So double check the pack dimensions vs how you intead to install them on your car / truck because in my experience they are longer & skinny'r than your average lipo pack ie... max amps or something.

And I also have the HV turnigy esc, yes they work great no cogging etc etc, and yes they have a really slow delay from a dead stop so if you think that is going to bug you save the $$$ and get the monster max.
