You don't have to balance them after every charge. Just make sure to balance them when you first get them. And then maybe evey other week. Depending on how often you use them. Of course, you could balance them after every charge. Theres nothing wrong with that. It's just during racing, no one is going to remember doing that when they'er toping off their batteries ten minutes before they have to race. So, just balance them a day before you race, and not worry about it the day you do race.
