looking to get --> http://modelsport.co.uk/?CallFunctio...n&ItemID=12425 . How long would it take to charge my 3200 7.2 volt and my 2200 one? (if it even will charge them) because im not very good with the maths on mah. And does it look like its a simple plug into wall and plub into batt and away it charges?? ta, really need a fast charger because my starter box eats batterys.
