If you buy from Maxamps, you could get two 3s2p packs with their 3000mah cells, so 6000mah total. That's $240 for the packs, and then you can get 2 Hyperion LBA6 balancers, $40 each, $80 for both. Without a charger, that's $320. There really aren't many (if any) chargers besides the AF109 that can do 6 Lipo cells for under $200, but the Thunder Power 1010C is $200 and is very good.
If you get the TP 10cell balancer for $100 and charger, along with the data cable to go between the balancer and charger, you would have a completely fool-proof charging setup that is advanced as it gets. So, for $300 you get a top-notch charging setup. Then, you would have $300 left for batteries.
