I am pretty new to electrics. I have 3 Thunder Power Li-Poly 1320mah packs. My charger is an Astroflight 109. How important is the need to balance the batteries? I was at the WRAM show this weekend and talked to Jason Shulman. He said the smaller Li-poly packs(1320 being pretty small) don't really need to be balanced. The guys at FMA said that balancing is one of the most important things for a Li-poly battery, regardless of size. Just wondering what some other people thought about balancing.

Thanks,
