Yeah, I don't have nearly enough batts! I have the stock 800mah HBFP batt and two 1000mah packs for it. I have four 2200mah for my 450s and a couple more on the way. I am going to start ordering one or two packs with every parts order and new heli.
A better quesiton is how many CHARGERS do you have?!

Anyone been around here much has seen my ghetto flight box with four chargers built into the top compartments!

As soon as HK gets the Turnigy 6S 5A back in stock I'm getting at least one of them and have no plans to pitch any of my current ones. I think a number of chargers is almost important as the number of packs you have.
