Where online can I get the best deal on lipo batteries?

Try www.hobbycity.com they seem to have good prices, shipping can be a pain sometimes but over all not bad.........if in stock.

+1. Turnigy cells appear to be especially inexpensive right now, and HK appears to have improved numbers in stock.

+2, the zippy flight max, and rhino's are usually the cheapest. I have had great results with the rhino's and flight max. Just don't place the order if it shows a negative quantity in stock!

+3. Have had nothing but good luck with Rhino and Flight Max packs from HobbyCity. Even in high draw apps (using them in a Multiplex Blizzard, large ducted fan jet, pusher Bobcat, etc) they stand up. I have over 100 flights on some of my Rhino packs, still as good as new.

I've been buying my 3S 2200 mAh from HobbyPartz.com for $15.95 each. They are doing a great job for me

I've had excellent luck with 3s 1300mah and 2200 mah Turnigy batteries from Hobby King. My 7 lb Showtime runs with 4 2200's - 2 pair in series for 6s then parallel the pairs together for 4400mah. I just checked out Hobby Partz and their prices look as good, but with fixed price shipping ($4.95) for any size order it will be hard to beat them.

Another vote for HobbyCity.

Good prices on LiPo packs and chargers.

Since it ships from Hong Kong, I wait until I can order 1kg worth of stuff, and get the EMS express shipping. It's about $5 more than registered mail, and gets here in about a week or less (typically).

HeadsUpRC has halfway decent prices on their Lipo packs. Just an "FYI".

I have bought several of the Blue Lipos from [link=http://www.tkqlhce.com/click-3922465-10680145" target="_top"]HobbyPartz[/link] and like the batteries. You can find coupon codes in several RC magazines for 5% off or free shipping which is only $4.95 - and I got the order within a week.
