It seems that there is an endless supply of different battery chargers out there. Can anyone recommend a brand that is good? Is balancing important? I was looking at some of Hobby King's chargers, should they be considered? My motors call for a 6S battery so I am assuming that I look for a charger that can handle that and more, I would like to run two 6S 5000mah or bigger packs for flying. Also I have heard of 6S 9000mah batteries but I have not been able to find any, any help here would also be appreciated. Thanks people.
