I've read through a bunch of threads and am coming up with different answers about LiPo batteries. From what I can tell, I need the following for a LiPo upgrade:

Great Planes LiPo 11.1V 910mAh 3S 15C Discharge Deans (GPMP0815)
Deans Ultra to Micro Deans adapter (GPMM3127)
Great Planes PolyCharge Lithium Polymer DC Charger (GPMM3010)
Hobbico 12 Volt Power Supply w/5 Volt Tap (HCAP0250)

I know this can be swapped with different brands and what not, but the bare bones seems to be:
1) battery
2) charger
3) power supply

Lessee...some questions...is there a such thing as a charger with a built-in power supply? Is 3-cell better than 2-cell? What's this I hear about a balancer? Is a balancer required? If not, when would a balancer be useful?

Sorry for asking a question that's out there many times over, I just can't seem to find the right answer. Thanks for any help. [sm=thumbs_up.gif]
