Hi yes the battery will be spot on for what you need it has a high C rate for good throttle punch out
As for the power pack it will run the charger that George linked to the white one 50w ,you can go for a bigger power pack but if its just 3 cell your charging it will with a added board charge 3/4 batteries at the same time in about 90 mins , but that will be the max on this set up , I charge 3 cell and 6 cell so have 2 chargers so have a 540w power pack , If you feel your going to be charge loads of batteries at the same time let me know and I will link you what you need but its not cheap
