that battery isnt the best nor is that charger. that charger doesnt seem to be promising. get yourself a peak charger with adjsutable amp rates. like a duratrax pirhana http://www2.towerhobbies.com/cgi-bin...&I=LXCLD5&P=ML and this batter http://www2.towerhobbies.com/cgi-bin...?&I=LXLWR4&P=7. that charger is one of the better chargers and that battery is a good deal. that charger that u linked isnt worth anything you would end up replacing it one month later. so you might as well save up for this one or a better one. that battery that u linked is ok but not the best off. i woudl go for that gp3900
